Performance Tuning

Well after months of reading on the internet and talking to many people about Tuners I felt that I would like to have one for my 2014 Silverado!The main thing I was looking for was to turn off the DOD/AFM which is very annoying with these new trucks if you have installed an aftermarket muffler because of drone.Everybody was telling me that this fellow called Lew was the God of tuning GM vehicles and I should hunt him up,I did and it was the best move that I have made from saving me some bucks on a package deal tuner,Walking me through the steps to tuning and loading files,To making my truck run smoother and stronger!(His website below)

Vehicle--2014 Chevy Silverado 5.3
Tuner--DiabloSport inTune Touch Screen Tuner
1.Canned tunes--Was stronger than stock and looked to get about .5 mpg better fuel mileage
2.Lew's custom tune--Stronger than canned tunes and pulled all through the gears even,Shifting was smoother and even rpm range between gears,truck seemed to start faster and just sounded better!Fuel mileage looks to be 1.5 to 2 mph better after Lew's tune.

**NOTE**-If you own a tuner or thinking about getting a tuner you should get with Lew and get the most out of your tuner.He really made it easy and great turn around with his work and customer service!Besides,He has some really neat stuff at his online store

I will second that. I also went with the Intune and a custom tune with Lew and have been very happy. It has made a very noticeable difference in my 09 1500 GMC with the 6.0l. I work out of town every week so I drive the exact same route every week, to and from work and to the seasonal camper every weekend. At idle my truck always had a little roughness in it, not bad but I could tell it was there and after his tune it's perfectly smooth. My mileage only went up by .07 mpg according to DIC but when hand calculating it was 1.1 mpg. That will help pay for itself very quickly with the number of miles I put on every year. The proof to me of the power gains were on the drive to the camper. I made 9 trips before the tune and 8 after so it's a compareable test. There were 3 hills that my truck used to have to downshift to maintain speed when the cruise was on but after Lew's tune it didn't need to downshift and didn't sound like it even was working hard, just sounded like i was cruising on flat ground. I know most people only believe hard numbers but that was enough proof for me. What also really impressed me is I could only email files on weekends because of work but he always replied within hours with a new tune, even on Sunday mornings!

I would recommend him to anyone.

Contact BlackBearPerformance. Maybe they have done tunes for the new 2014's now. Can't go wrong.

Camron, he got a tune already. He used the intune from Diablo and had it custom done. He was using an anecdote to express joy and praise for Lew

Right on Chris!I bought the package deal from Lew and saved some bucks.I really enjoyed working with Lew through the tuning process!

yep... I've been tuning the 2014's for a while now... ;)

Woops, lol. Guess I miss read. Lew, what kind of gains are you seeing and what exactly are you able to configure?

06MonteSS · November 5, 2013

dunno for sure on gains for the 2014's, haven't had anyone do a before and after dyno pull, heh...

but with all others, As far as gains go... absolute hp/tq gains are hard to predict... every vehicle is different... even if they're the same and have similar mods... location/weather, fuel used, elevation/altitude, etc etc all play a role... the same holds true for mileage gains - those variables, plus driving habits/style, how much highway vs city driving, etc all make a difference.... you could gain no mpg increase, or you could gain up to about 3 mpg increase... tough to say due to the variables in play... so there is no guarantee of any specific amount of hp/tq or mileage gains...

but I CAN tell you that you will definitely have a very noticeable performance difference/gain over and above the canned preset diablo tunes...

I have gained people anywhere from 12-39hp, and 10-23lb. ft. torque...and 0 to 2 mpg... again, obviously mods, fuel used, etc all played a role in who gained what...

can adjust shift points, shift pressure/firmness, how quick it shifts, torque management, disable dod/afm, speed limiter, remove throttle/WOT delays, fans, throttle/response settings, part-throttle and WOT fueling/timing, knock retard, etc etc. / plus more...
