Probably discussed before, but I don't find it by searching......

So, is there a "performance chip" (ala Dinan for BMW) to increase G35 HP/Torque output?

PS The salesman I bought my '05 Sedan from said there was......but he said a lot of stuff, know what I mean?

 

There's the Technosquare ECU reflash "chip". But it's completely useless if your running stock. It's only makes a difference if you're going FI or have quite a few mod's. All it does is raises the rev limiter, maybe more, not sure.

Run a search on Technosquare ECU on the forum, and check out their site, you'll find a lot of info on it.
