[QUOTE="Michael Hughes, post: 14769417, member: 99090"] First I need more info on your engine? port/polished heads, cams, head gasket thickness ect to determine you CR. Ball parking it using a stock engine 03/04 engines specs (95 mm bore) puts you around 10.5:1 I think. [B]What I would do If I was in your situation:[/B] 1. Increase the the Blower pulley to a 3.5" that should drop your boost to around 13 psi (using a stock crank pulley). 2. Decrease the crank pulley to a 6.5" this should drop your boost to 9 psi (with a 3.5" upper pulley installed). I would start here with car. I would try to tuning on 91 fuel with 10.5:1 DR and 9 psi of boost. If you run in to detonation problems while tuning I would try adding Torco fuel addictive, or a Water meth system to eliminate the detonation. If this fails (91, Torco, Wate meth) do you have E85 around you? [/QUOTE]
