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.

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.

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.

      Sure, but they do have some affordable options like the Trax, Trailblazer, Envista, and Encore. Some of these have a cheaper base price than the Civic, though the fuel economy isn’t as high. The main problem is that people WANT the highest trim with all the goodies and finance for like 7 years. That’s how ppl “afford” the more expensive vehicles.

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
