Guess what my 409,000 Mile M5 made. Oh and what's Gregs car worth?

[@peni80085]

342 rwhp, 47k$

[@terrancesimmons1]

338whp, 60k

[@crownhic6827]

305 hp and his car is worth whatever Carmax will give.lol

[@rohittaurus911]

About 350 Whp, And Ask Hoovie, he will overpay :P

[@isaacbenjamin389]

320rwhp and his car is worth $39k

[@justinsellsreo]

nice to see professionals actually fixing/improving cars, not just talking about it.

[@augustecomte3841]

These two are the best :)

[@StoneCoolds]

thats why we love LSC channel :D

[@MrOguuuuz]

Man I wish you could've added Greg's reaction to driving his car with the extra horsepower.

[@victorivansson3247]

Was waiting for just this. Such a letdown

[@gregnatonson6970]

Greg hasn’t been seen in days. By tracing his credit card charges at gas stations we can se he has been making his way toward Germany for a blast on the autobahn. Seriously, I’m totally stoked. It’s like the car I always dreamed it should be after seeing the BMW Guy Ritchie movie-ads when the car was new. I wrote a song for OJ as well.

[@GarryMcGovern]

Having not noticed that he only had 200 horses for the last 3 years, I doubt he actually drove it any differently AFTER the tune either: how could you not notice your M5 was pumping out less power than a Golf GTi?

[@johnbcardin]

Orfan Productions when you look at the torque pre tune it was around 260-280 in the 2000-3000 range which was not terribly far from the tube torque in that range. If he was using it as a cruiser/weekend car it probably didn’t feel off in that lower rpm range which probably masked the problem. I was really hoping we would get his initial impressions too.

[@GarryMcGovern]

@@johnbcardin Are you seriously trying to make excuses for this? That in 3 years of ownership - cruiser/weekend car or not - he never once accelerated past 2/3000 rpm? Yeah, ok man, you're right: it actually is totally understandable that he had no idea his car was 40% down on power the whole time.

[@ItsMikeArre]

I fkn love OJ man the man knows his stuff looking forward to the 400k Dyno run

[@Streamlined955]

That guy is the BMW Whisperer. He predicted what was going to happen before it actually happened every time. I wish I lived near to him.

[@robertastk]

Want to hear what Greg has to say after he drove his NEW M5.

[@jibmaster]

Mad respect to OJ and techs with this kind of brain.

[@FluidMotorUnion]

Thank you!

[@rammphillips3002]

Brian, Alex, I just watched this vid again cuz' I couldn't remember what was in it the first time I saw it. I literally got up out of my chair and genuflected to OJ as he made the last run. One of the best vids you have made! Bravo, bravo!

[@TheHeretic435]

E39 Guy here. Now this channel really is legit.

[@ShiftedPerspective]

Same here! I have a carbon black 2003

[@seanwilks7712]

We have a stable of e39s. Best chassis in my opinion.

[@celicasaur]

No word of a lie, my M5 had an Alpha N tune already but it generally was sluggish and very lacklustre to drive, even after fitting a 3.62 rear end. However once I'd done the IAT relocate mod and disconnected the MAFs, it genuinely started to come alive. It was improved for sure, but at the back of my mind, I thought maybe the cam sensors needed changing or something. But then today I wanted to replace my steering wheel, so I inadvertently reset the adaptations by disconnecting the battery. When I went for a drive in the evening, holy moly it really was a spectacular night and day difference. First gear is a blur and second gear gives me such a shove back in the seat that it brings a huge grin to my face. I wouldn't be surprised if my M5 showed similar gains on the dyno like this car here too.

[@NikoBellaKhouf]

I kept telling mechanics that my car was sluggish. Their response? "Oh hehehe you're just used to the power so it doesn't feel as fast."🙄😒 Great to see someone who knows what they are doing.

[@juanc5149]

Hoovies garage and his anemic e63 AMG needs to see this!

[@MilesHarrelson]

When they said, “It’s like you’ve been driving a 540i!” Hahaha only hurt a little bit, I’m okay. 😂😭

[@nastilyasperated2215]

I felt attacked

[@live2ridegsxr1000]

I've had an e39 540i 6spd for 15 yrs. That comment hurt my soul. Good news is, I pick up my e39 M5 tomorrow

[@KenitoElGrande]

Alex, thank you for bringing us some M5 content. I'm a AMG person myself but I've always loved the E39 M5 😍

[@S_Kane]

the hp gains brought a tear to my eye 😢. this was a beautiful day

[@torygyberg8837]

Well OJ has a new customer for life! Love it when OJ is in the vids!!

[@StephenJohnson-jb7xe]

This is one of the most joyful videos I have watched for a long time. I truly hope people recognize what a master OJ is and take their business to him. It would have been nice to see what, if any difference cleaning the MAF sensors made before the delete and tune.

[@rammphillips3002]

"...joyful..." I second that motion!!! Got misty-eyed watching the great camaraderie between all three of them!

[@westerberg9447]

Reaction video on the gain?!?! :D

[@typedrew]

Rasmus Werner Eliasson this please

[@factoryminis3437]

Make an addendum with him driving it, so we can see his reaction to 139 hp increase.

That's just sick. OJ is the M5 Man. Great vid.

[@Rick2010100]

The first thing i would have done by such weak performance: air filter check, cleaning the needle in the air mass sensor with break cleaner, check the sparks, run the car with injection cleaner addtitive reset the ECU and teach them new.

[@pauljoe780]

You must have done this so many times. But next time, if you use brake cleaner, first make sure you look at the big words on the front of the can. Then you`ll know you`ve picked up the right can. Don`t ever use break cleaner. That`s terrible stuff.

[@Rick2010100]

@@pauljoe780 The small needle in the air flow sensor can only be cleaned with hard chemicals and break cleaner is perfect for this, you dont need much, just a short spay and after soaking a second. It´s just about get rid of the dirt film.

[@b4804514]

Alex Always a pleasure to watch you go to your special place with these cars. This will educate lots of owners.

Thumbnail says "Try this one trick, it only takes 10 seconds" then I open the video and it's a 16+ minute video 🤭🤣 Great video though 👍

[@TheKeenMechanic]

Great video mate. I love the old school BMWs. I own a few BMWs (e38 740i&e39 530i) myself and currently doing some major work on my E38 740i. I would love to own an E39 M5, this has been my dream car since I was a child. Very educational video. Keep up the good work.

[@vbsource6209]

My E39 M5 made the same 343WHP on the same dyno (DynoDynamics) with Alpha-N. Besides tune and rear mufflers my car is bone stock too. Great video proving the point of this channel once again: enthusiasts over stealers!

[@FluidMotorUnion]

good to hear the feedback since people seem to dislike our dyno numbers!

[@danielwatts9803]

My 01' 530i sport is sitting outside waiting for me to tinker with its MAF... I'll be back

[@snowbaordguru]

Not a BMW or Merc, but I had a faulty DPFE EGR sensor that didn't throw a code on a Ford. Always thought it didn't feel right power wise and boy was I right. Massive difference in power and MPG when I changed out that sensor.

[@woodsoncircle]

I had a 2000 BMW M5 a few years ago- 2nd owner. Bought it from a Doctor up in Michigan. I recently sold it ... like a fool. Still a beautiful car.

[@DarthRaven2]

We need his reaction of driving the car ..would've been awesome to see what he thinks after gettin that much power back !

[@LewisDijs]

Hahaha! “You’re gonna drive easy, right?” “NO!”

[@grantingapex8169]

best car channel by far thanks

[@Bsaint]

Great video just wish they would tighten those rear straps, waaaaay too much movement and slack in the rear. It’s coming off of the rear roller

OJ is the MVP!

[@rayquinn6886]

Awesome Video as usual, there was only one thing you forgot! I would have liked to seen even a five second clip of him driving the car for the first time after the tune. I can speculate that he was smiling like the Cheshire Cat and laughing like the Mad Hatter! Great job again!

[@rammphillips3002]

I teared up when I heard that... Wow, that was priceless!

[@erikwallebom]

I've had two E39 M5 and both had dirty MAF's. To check the status of the engine power output you can use the service menu in the instrument cluster (google it). Find the real time liter/hour measurement. At full throttle in 3rd gear (or whatever gear) at max rpm it should consume about 160 liters/hour. Mine did 100 liters/hour. I cleaned the MAF's and it was restored to 160l/h and surely felt quicker.

[@zimzimzimmer]

Loved seeing this I wonder what Gregg’s reaction on the road. Just shows like you said how important it is having a tune now and then. I’d say yours with mods 300, and his cars worth approx $20,000?

[@audiovideotech9777]

As a Pro Detailer, I know Jason at Chicago Auto Pro's where he works at. Also do I see a dual head rear laser jammers over the rear plate?

To help diagnose that “sluggish” feeling without a CEL, you can check your volumetric efficiency. Several videos on KZbin on how to and what to expect.

This is quite interesting every couple months I pull apart my MAF and throttlebody and clean it usually about every third oil change on my Subaru I have the flat six, but what is weird is the best thing to do is reset the ECM by disconnecting one of the leads to the battery resetting everything after doing the cleaning!

[@hashimkay140]

That's amazing, should have gotten the guys's driving impressions after the gains!

[@deplorabledave1048]

My dyno tuned E46 M3 makes 300 to 310 RWHP depending on temperature. I have seen naturally-aspirated versions of my S54 straight six make around 400 horsepower using special intakes and special tunes. It takes a lot of money just to gain that. Not sure how much. One guys tune came all the way from Dubai. The air boxes are all carbon fiber and cost a small fortune.

[@yamahattr6006]

Nice job
