I have been looking at this engine management stuff and was curious how it would effect a mildly modded G35. I already jave a z-tube and stillen CAI, plus a grounding kit I plan on adding a spacer and true dual exhaust. I was told by someone else that I can gain 15hp to the wheels with just a piggyback system on a stock car. Is this true? Any and all help is appreciated!

 

I run a Unichip and am very happy with it. Before and after dyno's showed that I'd gained 12 whp with gains across the entire rpm range. There is still a little tuning left, so there may be a big more power to be had. My modifications at the time were: K&N filter, Z tube, 5/16" Motodyne plenum spacer, UR pulley, ForcedFed headers, Gruppe-S y-pipe, and coupe mid-pipe. I've since added Hondata intake gasket and Fuji exhaust, but haven't re-dyno'd and gotten the final tuning done.

Hope that helps.

 

I gained around 14whp with just the UTEC on my bone stock 05cpe and another 14whp w/ res. test pipes...the dynos are floating around somewhere on this board.
