going to get myself a new ecu , wondering if there is any difference between m2 or pettit in how they tune the ecu. any one better then the other? i have done a search and didnt find much, any help appreciated.

 

generally both a good, but Pettit tends to be a little more aggressive, but still safe and tend to make a little more HP with every thing else equal. Brian's **** about making sure it's safe and tunes on the conservative side but both would be a safe choice.

I can only comment on what I have (Pettit)
And I love it, only thing I would recommend is to get a good electronic Boost Controller to keep their 14.7psi boost level down to a safer level. (if your on stock Inj & IC)

With Full exhaust, intake and 10psi & 12psi my car was running very rich (10:1 from 4500rpms to redline)
which was safe for the road racing event I attended, but I knew it would be somewhat rich because its set for the mods I have PLUS an aftermarket Intercooler. And Im still on the stocker. (not for long if someone will sell me thier used smic.
