It's not getting the air in that it expects it should... or some sensor is fubared from something, maybe exhaust leaks......

 

its easy.. Check your pm's You o2's are bugging out and are seeing a more than likely "false" lean condition due to the amounts of overlap and cam LSA. So the o2's think the car is running lean, so they are dumping a butt-load of fuel. Might want to consider an open loop tune..

 

I know every car is different but I have a 11to1 355 also and i make my power at 12.5-12.8 AFR... Just my .02. Mods and numbers in sig.

 

FYI I picked up right at 50 rwhp locking my converter.

 

Wow id be a happy camper if i gained 50 rwhp...that would put me at 380 and still be way rich...maybe there is hope for close to 400 rwhp.


Thanks for all the help guys
