Diablew Tune

Vetteran · October 13, 2017

Lew did my tune last February, you will be so glad you did it. Shift points are much better and the SOTP meter will respond favorably too. Enjoy the results!

I am looking forward to it. DiabloSport needs to get on their game with updating this thing to work. Apparently the guys with the i2 it works fine. Just us with the newer i3 are having the issues from what I have seen

SippiSierra · October 14, 2017

Update: I went over and took a peek at the DiabloSport forum and they posted that there was an update. Fired up my i3 and downloaded it. Took the tuner out to the truck and there it is, recording as it should. I will wait until tomorrow to do a log for Lew as he said to do it during the heat of the day and not at night when it is cooler. Next it should be getting the customization from him and then uploading that to the truck!

The logs were done and sent to Lew to do his magic. I will update when I re flash with the custom tune.

I've had the Intune i2 since Jan, 14. I've used the diablo tune, and just messed with the parameters inside there. I am curious as to see what differences would be made with Lew making a custom tune. So hopefully once issues get fixed with the data logging on your tuner, we all can see the results.

WOW. So DiabloSport finally sent out an update last Friday and I got to do my data log Saturday. I sent it in to Lew Saturday evening. He sent me the custom tune this morning while I was at work. I got off and came home, uploaded it to the i3 and put it onto the truck.

Lew's tune puts the canned diablo tune to shame. The truck is is amazing now. It is like someone sat me down and interviewed me on how I want my truck to behave and now it is doing it. Shifts are perfect, power is there when needed, no more AFM, Shakey idle is GONE, I only drove around for about 15 miles but I am HIGHLY impressed with him, his customer service, and the product. The money was WELL worth it. Next step is to do the WOT log for him in 150-200 miles. I will report back on that one as well. So far, so good. If anyone has any questions let me know!

I hate you. You aren't helping my case. So the change is THAT noticeable? Exactly what I wanted to hear. I might, no, I will get a custom DiabLew tune.

For me it truly was that noticeable. I am extremely impressed. Let me know when you make your purchase!

Did you notice a mpg change? Other than the honeymoon period when you were trying it out,lol.

Are you 6.2 or 5.3?

I made the "mistake" of going to a 5.3 from my '14 6.2. Really notice the power difference.

i put on 40-45k/year and mileage is a bit of a factor.

Are you running 87 or higher?

I have noticed a MPG change and for the better with AFM on I was averaging 17.2 mostly stop and go getting to work and some light cruises down the highway on the weekends. Now I am seeing 19.1 average over 800 miles of the same driving. I run 89 octane from Chevron or Shell but 99% Chevron. I have never owned a 6.2 but my 5.3 has woken up tons. If I need to move down the street or merge I have up most confidence in it. Lew is a great guy and he truly cares about dialing in your truck the way you want it.

Thanks Sippi, I will look into this. Glad its working out for you.

I have just downloaded Lew's tune for my truck, but when I got to custom tuning it only shows the ECM, not the TCM. Anyone having this issue?

Hearing this makes me want an early christmas gift for my truck lol!

My lifters went out earlier due to AFM... dealership fix under warranty, i did lift the front 2 inch and gotten 275/60/20 nittos and man my truck feels like it’s a v6 it’s just slogging! it’s always in v8 mode and i feel like the shifts are hard and the trucks just can’t pull...

Im thinking this tune could fix this the problem and let the truck drive how it’s suppose to be.

But my question is how’s the tune so far, have you had any problems with updating it? and also i’m not to familiar with tunes, the tune you got was the basic diablo tune which was the diablo tune canned 87? and you then got logs and sent it to Lew to get a custom tune?

Also the 87 is the gas you have to run for the tune?

Sorry for many questions just wanna learn. :chevy:
