Yeah I'm still running the 19's but w/ FMU (12:1 disk). FP is 75-80 at 5#'s of boost. I know I'm at or close to maxxing out the stock inj. and when funds become avail I'll step up and get correct tune for setup. But this prob has been there long before I did any upgrades. I think I'm looking at this wrong. The sound I'm hearing may be the ping that's associated w/ the 94-95's. I've heard several things others have done to correct that...upgraded fuel pump (190, 225), changed sensors (I think ACT or ECT not sure which). Any ideas. Thanks for the input so far guys.
