On my s/c AP1, when I was running the comptech dual with a resonated test pipe, I was running 12.0 AFR (tuned) under WOT, then I recently swapped the stock cats and stock exhaust back in, and now I'm reading 11.3-11.5 under WOT on the wideband...BUT I did add a high flow fuel pump prior to reverting back to a stock exhaust, so having the exhaust/tp probably only leaned it out by maybe .3 points.

InlinePro has a dyno, but since you are in Howard County, I would give TPC Racing a call. They are in Jessup, and mostly work on Porsches, but they do have a dyno.

Hope that helps some.

 

Cool. Thanks. I'll give them a call. I probably won't be able to put it on the dyno until after the Redline and NASA events though.
