You always read my mind. TU gets here Tuesday! Best B58 channel on YT.

[@TeeZB58]

I wasn't going to do it if I had to splice my car oem wiring then I found a video somewhere of flipping the plug! And yes loosely attach everything together then torque down together! I had to learn it myself!!!! 💯

Just ordered a tu pump. Thank you for the info on our platform!

Updated DIY coming soon 😬

Can’t wait! Getting ready to order custom trans tuning from watching one of your other videos!

I got my TU Pump from Puma Speed Performance in the UK brand new for $425.00. I haven't installed it yet. I'm waiting until spring weather gets closer. Then I'll install the pump, CTS catted Downpipe, Remus cat back, and the XHP Tranny tune. 2018 G30 540.

[@m5nut]

I have a TU pump ready to fit, but *_I have a question_* ....After a little story/rant sorry: I previously asked a well regarded BMW/Mini specialist to fit the TU pump during my car's service. He was at the point of bolting it to the head and called me to say he was apprehensive of torquing it down. He reckoned that, because the TU pump has a thicker flat bottomed plate vs the stock pump having a thinner plate and indentations around the bolt holes (to accomodate tall cone shaped o-rings on the gasket), it would require more than 12NM to fully seat the pump in the gasket and be leak free. As he didn't want to risk stripping the threads, trying to get it to seal, he didn't fit it (even after watching your tutorial vid); proceeded to re-fit the old pump and charge me 2 hours labour on top of my service bill 😡 It was suggested that if there's a TU gasket (which there is) he would be happy to fit the pump with the 'correct' gasket (costing me another 2 hours labour). As a TU gasket was pennies I bought one, so I could see whether it had the 'all important' thinner o-rings (which it does, they're flat not conical). The issue is: the outer shape is not the same as the gen1 and I think it will be incompatible with my cylinder head. Of course I won't know for sure until the pump is removed again. As I'm not paying someone to do a job twice, I've decided to fit it myself once I have a day off with nice weather. It's just the 'issue' he raised, is now worrying me the longer I think about it. What do I do? Do the original gasket 'cones' compress easily enough so the outer gasket seals up fine at 12NM of torque? It seems everyone and their gran have fitted these hassle free and I'm the only one stressing out! 😳🙄🤪

[@LuizPauloDT]

Sounds like overreaction. I have just fitted a TU pump and there is plenty of thread engagement, even with the thicker flange. Thread striping aint a problem for sure. Most important thing IMO is to tighten it 90 degrees max per bolt, alternating to not damage the shaft. Acc to ISTA, when working on the fuel system, it is also recommended to cover the ignition coils (remove if necessary), as fuel contamination on the silicone hose can damage them. Just follow Kevin's DIY and send it!

[@kern417]

Everybody I know has used the stock gasket. I don't see it being an issue.

[@m5nut]

@@LuizPauloDT Thanks bud, that's what I thought. Sending it Sunday if the weather is kind to me!

@@kern417 Appreciate the response Kern. 👍I knew he was being over cautious. Great content as usual.

[@fatalmastermind]

Hey Kern, I was looking to get your opinion on whats going on with my 2021 Supra. The only mod I have is a Active Autowerks catless downpipe and am experiencing a decent amount of smoke pouring out of the exhaust at random points usually when the vehicle is about to come to a stop or is at a stop, and the car only has just over 1000 miles on it. Do you think this could be related to the PCV system?

[@kern417]

It could be. Do you have any codes or anything? And you're saying the car itself only has a thousand miles, or it's been a thousand miles since you installed the downpipe.

[@dennybrows9916]

Could just be the downpipe itself. When it reaches those extreme temperatures for the first time, smoke can come out, typically white smoke. After driving it around, the smoke will go away completely

[@fatalmastermind]

@@kern417 The car only has just over 1000 miles total mileage on it. I for sure have codes for deleting the cat but I have not read them as of yet, I do have access to snap on scan tools though. My though was; I may have revved it a little too hard before getting it tuned and messed up the internal pcv system? I'm not sure what else it could be. Thanks for the insight!

[@fatalmastermind]

@@dennybrows9916 I have had the pipe on there for a while, it would not produce the large amount I am seeing or at random points. It is most certainly burning oil for whatever reason.

[@kern417]

@@fatalmastermind yeah potentially. Thick smoke is usually oil

Great video buddy! Have a question- actually running mhd stage2 98ron. Is it worth to upgrade pump to TU and go stage2+ while i will be running only 98ron? Thx for answer ✌🏼

[@kern417]

Yes. I Will be posting a video soon with my testing

[@andyp806]

Excellent vid as always, you continue to provide a great service to the B58 community 👍 I have a M140i, currently Stage2, considering going Stage2+ this year. Are there any benefits of using a Dorch Stage1 over the TU HPFP? And would the Dorch Stage1 produce a slightly different power/torque curve compared to the TU? Future plans to perhaps put into consideration of the HPFP choice.....undecided if I will be going Stage3 or not, if I do it would be a smaller hybrid turbo, possibly the LIttco L520.

[@kern417]

No real gains from TU to DS1

Hi, I have a TU pump installed on my Gen 1 and intend to install a pure 800 and run only 94 Oct. How much power do you realistically think is left on the table with this setup as opposed to installing a Dorch Stage 2? Thanks

you won't make much more with a dorch on pump gas. the TU is plenty

[@FQ1998]

You probably never got this question brother, but why does BM3 have a stage 2+ 91 octane whereas MHD only offers a stage 2. One shows huge gain with 91 octane whereas the other doesnt?

There aren't really much gains to be had with 91 so mhd didn't make a tune for the tu pump.

Can a tu pump be fitted to a stock (mppsk) 340i? I know it will provide no gains at this point but I will go stage 2 later on just wondered if it’s ok to fit before tuning or is it best to do at the same time?

Hi, I have a 540i and I recently upgraded it to a stage 1, running 370whp. I also substituted spark plugs to new stock ones and cleaned up fuel injectors. However recently an intermittent failure occurs, mainly after after continuous time of flat out driving, in which the engine fails and the car gets to emergency mode. I still didn’t get to the cause of the issue, but I suspect it may be something related with a hpfp. Do you think upgrading it to a b58tu would make the system safer and avoid potential issues? What else could I do to improve reliability?

you need to diagnose the problem before throwing parts at it. scan for codes. run a log. and go from there.
