[QUOTE="tfoster405, post: 5346493, member: 18801"] Thanks for all the info... My car has been essentially been stock for 4 years (CAI and Cat-back only) Last week I finally installed a RR 2.93 and Amazon's SCT flash tune. The car seriouly "woke" up. G-tech readings went from 380-390 to 445 hp in second gear with some spin. After only a few hard run through the gears and looking at logged data from the SCT, all looked pretty good. MAF was at 4.8 volts, Fuel pump duty was at a max of .84. Short term fuel trim during WOT was at .82 which I understand to be the factory O2 sensor voltage (plenty rich), Factory boost sensor was reading was 56 (I think inches of mercury) ~13 lbs. Then with the car really hot, I stop to listen to the engine and I thought I heard "some" ticking, not too loud, but definetely a ticking that I never heard before. I turned the car off, let it cool off and later started and drove it and did not hear the ticking. So far, has not come back. [/QUOTE]
