I was driving around today and started to notice a "tick" sound coming from my engine. I only heard it 2-3 times tonight. It mostly happens around 4k in 2nd and 3rd gear at wot. I've also noticed that my boost is around 12psi in first and 14 for the rest of the gears, is this normal? My only power mods are scoobysport dp, apexi catback, and samco IC pipes. btw its an 04
Last night I got a cel from the downpipe, but reset the ecu and now it is gone. After the reset my car felt slower. Could this be a product of the ecu "learning" and now it is going to pull timing?
