Went to the dyno today....and all night. Car could not put down more than 277whp. I was at 14psi. My A/F was reading 14.8!!! I have Apexi N1 duals so we disconnected it and stuck the sniffer in the cat(straight pipe) still read 14.8. Change sensors on the sniffer and stil 14.8. clearly sniffer is broken, but Im still pissed. 277 at 14psi rich or not sucks johnson. It was a dyno jet.
