DiabLew Tune: Is it Worth it? Custom GM DiabloSport Tuning Review

[@roykowis223]

i have been using him for custom tunes on several of my vehicles.im very happy with his tunes, top notch customer service as well. you cant beat it for the money.

[@johnnytsunami6185]

had my 2013 silverado custom tuned on 91 octane by lew and boy oh boy well worth buying the tuner and purchasing the custom tune. i have so much more power and a added bonus im getting 16 mpg compared to 14 before the tune

[@petes_mk8r]

Damn, you drive that thing like a boss

[@Dylanclemmer315]

Thanks for the video, I’m looking into the diablew tune and this explained it perfectly, never knew a Silverado turns into a race truck the way you drive😂😂 awesome vid man thank you

[@jamesyork6023]

Thanks for the review. Had a Diablo on my last 5.3 and didn’t care for it. Just picked up a 2015 5.3 Z71, I’m planning on the Airaid MIT, JLT Catch Can, Black Widow Race Venom Muffler, and a i3 sent to Lew. Also going to do a motofab 2.5”/2” level kit, with 285/75’s on the stock 18’s. Your truck is very badass. Love the way it sounds and that you use it

[@devinharding144]

I actually have this exact set up for my 18 sitting in the house ready to go on 😂 race venom muffler, jlt can, airaid mit with drop in filter and the level kit.. I’m about to buy the tuner as well! Thinking bout if I want long tubes or not

[@jamesyork6023]

@@devinharding144 I just added the level, JLT, MIT, and an AEM drop in, still deciding on exhaust, and decided to do a local tune instead of Lew since I’m lucky enough to live close to LS guru’s, lol. I thought about long tubes, the only ones that were affordable and didn’t sound “tinny” like the speed engineering or TSP were the Doug thorley tri-y’s. I’d advise against headers, just another place to leak.

[@devinharding144]

@@jamesyork6023 yeah still on the fence about it.. I’ve already got the race venom exhaust so looking forward to putting that on! I’ve got a local tune guy that does great work but Lews tune is nice for the fact that you can re download stock map and dealer not being able to void warranty for it

[@jamesyork6023]

@@devinharding144 yeah that’s true. I had a glass pack on my 16, muffler guy wants to do it again and I’m really wanting a race venom but he says it’s a waste of money and I’m trying to stay cheap. So we will see lol

Great video. I have a 14 Silverado 5.3. Def going this same route. Thanks man

[@mudztwitch6028]

Hell yeah brother....

[@725outdoors]

Thanks so much for this video. I have the i3 on the way for my 2015 5.3 denali with the 3.08s. Have basic bolt ons intake and borla exhaust going on tomorrow. One thing I've always hated about the truck is the 3.08 gears. Looks like your truck gets up and goes very well. Im excited.

[@BadAssEngineering]

Tyler Hooyer I have a love/hate relationship with my stock 3.08s but the truth is that my truck is too fast for my brakes if I really push it. Shorter gears will just get me in trouble LOL

[@725outdoors]

@@BadAssEngineering true haha. I found that just the 87 tune with the i3 helps coming to stops a bunch with the little bit of added engine breaking when it drops the gears. Before I had to get the brakes decently hard.

[@Eklectic1]

Good video bro. Short sweet informative and direct.

[@sogood4u489]

Can someone send me an old tune that turns off rear o2 and erg

[@joegallahue3698]

You rock man

[@jordyc4593]

Hahahaha I love your analogy of giving the engine a lil yayo 🤣 My tune from lew has been amazing had it on my 5.3 for about 6 months just have CAI and 3" single cat exhaust at the moment, found your page trying to find more information on the speed engineering LTs, my only worry is they might make the truck too loud which I dont mind but my wife might kill me, but from your videos it doesn't seem like it is that bad, maybe she will enjoy it lol!

[@BadAssEngineering]

With the correct mufflers and X/H pipe you shouldn't have a problem

[@tonycee4628]

How do I get in touch with Lew?

[@Z71Angel]

Hey man you think if I put long tubes on my 05 5.3 does this tuner let you put the stock tune back on and if I need to take them off for smog will the smog place detect of the computer being tampered with this tuner?

[@BadAssEngineering]

You can switch back to stock as easily as tuning it, I don't think they can check for the ecu to have been tampered with

[@Z71Angel]

@@BadAssEngineering oh okay bro thank you for the help!🔥

[@curtisschuler4287]

well done

[@j911perez9]

I have a 2016 single cab Silverado 5.3 where can I get this tune ?

[@BadAssEngineering]

DiabLewTune.com, and the tuner can be purchased pretty much anywhere

[@brianlopez7228]

Gas must have been cheap in Venezuela at the time of this vid. I returned my Tahoe 5.3 to stock when gas hit 4.90 in Washington DC. I drive slow now.

[@BadAssEngineering]

I started riding motorcycles lol

[@Tazman1966]

On a vehicle still under warrant, are you able to take it back to stock with no signs of tampering if you need to take it in for anything?

[@BadAssEngineering]

Tazman1966 yes

[@thebaron8783]

Which engine oil do you prefer .? Love the dogs 👍 & the truck 👌

[@garneylester8530]

Did you use the hard shift or firm shift

[@BadAssEngineering]

I don't remember, but I think it was the firm shift. I don't know if Lew programmed that to be dependent on throttle position

[@Ruben-us2kf]

i have the same exact truck 2015 single cab with 5.3L...how is your transmission? Is it giving you any issues?

[@BadAssEngineering]

Ruben Graham Super solid and zero issues. It's been a really good vehicle** for me for the past 4 years

[@Ruben-us2kf]

@@BadAssEngineering Nice i've had mine for 3 years but my engine light came on due to transmission. It only has 50K miles and the mechanic said it was weird that the engine light would come one, i'm wondering if its the mod that input some years ago. Anyway love the sound of your truck i'm still debating to lift it slightly.

[@BadAssEngineering]

I changed my Transmission Fluid and filter at like 40k miles, just to freshen it up. Also, if you have a stock exhaust try wraping the exhaust pipe that goesn under the transmission with header wrap; that will make the fluid take longer to heat up, extending the fluids life. That exhaust pipe literally cooks the transmission from the pan

[@mahjayedagoat6031]

Do you have the download file for this tune ? I’d pay you for it
