Ok, left a driveway and got some wheel spin and my engine made a horrible noise and then major lose in power. Was only at 6 lbs boost until I installed bov. Then it jumped to 8. I started getting fuel cut and I believe detonation in 2nd gear and up pulls. Here's a breakdown on engine.

6 port keg
s4 T2 lim and uim, ecu,boost sensor,550 injectors,afm, and fuel pump.
N/a emission harness
s5 turbo
2 1/2 tb exaust
Ported s4 throttle body
Blitz bov
Koyo rad

Did a compression test and both rotors have 85-90 lbs with three even jumps in both housings. I started it today and it sounds like its running on one rotor. Any ideas??

 

Maybe a plug for an engine sensor or fuel injector got unplugged. I'd go over all the connections in the engine bay.

 

i would check your injector connections

 

Basic stuff you should have already done:

Check for spark on both rotors
Check for fuel on both rotors

 

Ok so I pulled off uim. Sure enough my rear housing primary was barley hanging on. put a new metal clip around plug and plugged it in. It took a while to clear out from all the excessive starting. But it was the problem. My wallet feels a lot better now. Thanks guys!!!!!!

 

Perhaps that was karma telling you to be a little less hard on the throttle while leaving a driveway.

 

I couldn't agree more!!

 

I would also avoid anything that causes detonation
