got new baselines today with the iforged, but ran my old wheels to compare to january's dyno and establish power loss for iforged (see other thread). After 6 months, I have interestingly lost some mid range torque, but gained a lot on the top end.

Mods (then and now, no change)
Hyperground
Injen CAI
Custom Ypipe and flowmaster (definitely costing me hp)

I'll let jtree007 post about his results, with same mods but stillen exhaust, but lets say they are pretty damn impressive.

 

Nice... Just like mine... No loss of power!!! (more than 6 month w some mod and never loss any HP)

 

Well that looks like a better baseline than you described in the other thread.

I say just go with a dyno proven, company tested Y-pipe and exhaust on your car. Top Secret and Fujitsubo make Y-pipes or you could just go with Borla. Good luck!

 

either gonna go stillen or borla. You can see his graph under the same titled post at 350zfrenzy, but jtree007 got 257hp with grounding kit, injen cai and stillen exhaust.

 

next test is the technosquare. My ecu is sitting in a box right next to me, shipping out tomorrow to them!

 

actually, I've only increased to the point where I was before any mods. so the 4 hp loss I initially got from the injen/exhaust have gone away. maybe the ecu works the other way too, sensing to little airflow and making more power!
