Tuner
 

Hey there! I have a 2007 Monte Carlo SS & I have been looking at different tuners to install on her. In particular, the one I've had my eye on is the DiabloSport T1000 Trinity. She does have a CAI (K&N) and 3" exhaust. Has anyone used this tuner or similar one's? What do you suggest? I'd like to know your thoughts; the good, the bad, and the ugly.

I don't agree with any hand held tuners. Either buy a mail order tune or have it Dyno tuned.

Hello and Welcome to the MCF! I agree with John, the hand held tuners are a gimmick, do some research on them and you might agree. I think what John says doing the "Mail Order Tune" is the most cost effective option. You pull your cars computer out, mail it in and the tuner custom tunes it to change the parameters of the computers factory settings. They can delete the factory speed limiter, change tranny line pressure shifting points, etc. And I think some tuners like on the forum here you just give them your Montes VIN number and they can mail you a computer tuned to that VIN, you swap them out and mail your old one to them. It's actually pretty little money in my opinion. :cool: Here is a link to a member who can square you away.

You don't have a 3" exhaust from front to back do you? Or does it start 3" after the CAT Converter. That's way to much exhaust unless you Turbocharged / or highly Supercharged. So I bet it's only after the converter or just the tips after the mufflers...:confused::confused:

Greg he is in a 2007 SS so he has the ls4. 3" exhaust is fine.

Hey Greg, thanks for the share on my PCM services. Unfortunately, as much as I'd like to help, I don't have the ability to work on the '06/'07 Montes.
But I agree with the logic of finding a mail order service familiar with the LS4 drive train and tuning for it. I believe companies like OverKill and PCMforLess can work with it.
