My 6 roadster went in today for a dyno run and needs wings dual CAI install. I wanted to have a good baseline of the rwhp before and after all the mods I have planned. The stock run was 287hp and 272 tq. The CAI produced 299hp and 271 tq. I hoped for more but you can definately feel it driving. The shop said they thought the car was runnning lean at 12.8afr but they are not familiar with this engine, so I am hoping someone can tell me what the ideal afr would be. From what I have read it looks like 11.8-12.4 but I'm not sure if different mods change this. Any info. would be greatly appreciated.
