Had the car tuned + auto, side mount CAI (APS designed) extractors with 100 cpsi cats as above and GTS/Maloo catback with standard mufflers.
I'm very dissapointed only made 251rwkw on E85. But more so driving the car Less throttle response, less torque until 4000-4500rpm then goes like I expected till it drops off at 5500.

I trusted Frank at APS when I had concerns with the extractors and CAI design. Now the excuses: the blue stock line on the dyno sheet is after everything was installed and the red line is with a tune, Its a new Dyno its tight it reads low, the x pipe is restrictive.
My gut tells me my car was rushed and probably barely spent any time on the dyno (too many big dollar cars there to care about mine)
I could of saved a $1000 and had hsv extractors instead.
Any thoughts would be appreciated
