Best Tuner on the Market

Reviewed By Steven Y (Haleiwa, HI) Reviewed for a 2015 GMC Sierra —6/7/2016 1:52 PM

I owned a I-1000 and it was ok. This newer on is faster and you don't have to press extremely hard for the buttons to respond.Also going back to stock is way faster than the first series.

Tuner has very good tunes an abLe to upload custom tunes via download or micro chip. Can't beat this tuner the Trinity customer service SUCKS!! I emailed them asking how to make the tuner to power down once the ignition is turned off after 4 days I got a response from them, all they said is to unplug it from the ECM port. When i mentioned wanted to use the gagues feature while driving the CS Rep came back with "sent it back where u bought it an get a refund then". That isn't cool at all.

So I bought this tuner not knowing anything bout it. I was worried I might not know how to properly install tunes and mesure paeameters. Well after a while of research I found out how to installl tunes I tried the 87 octane tune. Right away I felt a huge difference my truck was awake my acceleration was different more responsive. So then I did more reseach found a guy by the name of lew or diablew tunes predator gives u the option to install custom tunes and diablo.com gives u the information you need to find people that can make a custom tune for ur car/truck. I found lew won't go into much detail but he tuned my truck with balls. There is so much thing u can do with this tuner if u have mods on ur truck a custom tune is for you. Or even stock vehicles can enjoy this great product.
