Just Installed Diablew Custom Tune

[Built2crash]

Just received my custom tune from Lew the other day, only put a few miles on it so far so I cant give much of a review yet. But I can say its a different animal. I will give a review after I put a couple hundred miles on it.

Have no experience with any other remote tuners, but I can vouch for Lew. His customer service is top notch. The two main things I noticed; the TCU tune is phenomenal and isn't searching for gears all the time when you stomp on it, and the low end torque is snappy like it should have came from the factory. My butt dyno approves!

I totally agree with boettcher40, I also have a Lew Tune and my truck was like Really?  What it should have been from the day I drove it off the lot. Lew is top notch with his customer support and his tunes.

Those are the first things I noticed as well. I will probably do some 0-60 runs while doing the WOT logs just to see what it clocks at. I know what it was stock so I have a baseline. And yes Lew has been great to deal with.

Does he sell tuners ready to go? How do I contact him? If for nothing more than fixing that blasted gear searching when you put it to the floor.

 

Thanks

I also have a Lew tune. Nothing but a positive interaction with him. His communication is great and quick with replies. Very satisfied with tune.

I also have a Lew Tune.  Yes he sells tuners and tunes.  Lew is the best, service is fast and his tunes are spot on. I have 2018 GMC Sierra SLT 4x4 with 6.2l and he really made it a different truck.

You will not regret using Lew.  Just my $.02

I see on Lew’s site that he doesn’t disable/alter emissions related item...so I take it that you still have the v4 mode after one of his tunes or does/can he disable that ?

Just trying to decide if I am going to get a range AFM disabler or go with one of the other “tuners”.

He turns the AFM system off so it’s full time V8. That has nothing to do with emissions.

I am curious if a tune will help with the 8 speed clunk?  

[Built2crash]

Only people with the 8 speed that have the tune done can really answer that question. That being said I would guess he can tune that out.

[Victor Sosa]

Can he remove check engine light after removing cats of exhaust?

I've thought that getting a Lew tune, but I don't think that he can tune the 2017+ 8 speed TCM. I know the tune in my 2015 was awesome and the "new" shifting points made the truck much more fun to drive. So, I would be curious for the guys that have a 2017+ 8 speed, did the Lew tune change when the trucks shifts?

I don't see why he couldn't tune the 8 speed. The intune i3 8246 supports 17+ 5.3/6.2. I'd shoot him an email just to confirm.

It supports the engine only.

 

The TCM must be unlocked for you to do any tuning on it.
