Did a cam and valvespring install at a local shop recently. Did a before and after dyno same day. results were stock w/ lid, cut-out, ram air kit 320 hp 333 tq sae corrected. after cam install car rus perfect no codes, great idle, but on the dyno we lost ALOT of power best was 295 hp 316 tq. cam specs are pretty mild. it is 222 intake 230 exhaust .534 intake .544 exhaust on a 114 lsa. I cant see this cam losing power if anything it should have stayed the same lol <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Please help, We have checked everything we can think of. Car runs great otherwise just isn't making any power. Cam was installed dot to dot, valvespring heights were set according to spec.

Thanks in advance
