@zeneffect I left the dyno at 201.09 HP and 144.63 TQ with the N1s There may have been a tiny bit more there to be had with some more tuning but the car was having temp issues. I think I need a new radiator.
Theres alot more to the story ,but you all will have to wait.I had alot more issues than you did installing and fitment wise....but its on and done.

So in a nutshell...no MAJOR gains with the header over ssac on my basic bolted setup...but it does have a different curve and the AFR is gonna change.Lowend power is al little better and it held power out a tiny bit longer.
Actually bolton back to back did yield 4hp gain without tuning on stock cams.
