Hey guys,
had the MSP for a few years now and it has been completely stock except for the "spring" mod.
So i installed a mechanical boost gauge last weekend and a catless TBE (i actually just had the cats removed and left the stock racingbeat muffler bceause i didn't want anything obnoxiously loud---just wanted to free up some airflow).
Came home and reset the ECU (disconnect battery, pump brakes). The car ran great for about a week---no CEL, slight backfire here and there, and boost was holding perfectly at 7 to 7.5 in 3rd gear.
So i got in it the other night to go for a drive. let the car warm up and everything, went to get on it in 2nd and overboosted to 10psi and the fuel cutoff. Drove around a little bit more (very carefully watching the boost gauge) and then got on it a few more times----no problems at all. All back to normal with the boost holding nicely at around 7.
Get in it today. (remembering my overboost issue) to see what happens. Once again, go to get on it---overboost. But this time i was VERY careful and watched the gauge the whole time and had my foot ready on the clutch, so as soon as it started to go up i let off and clutched in (hit about 8 or 9psi).
Drove around a little more----same thing, different gears. I never let it go past 8 or 9 and always clutched in. But this was happening at QUARTER THROTTLE.
What gives!?
Side note-- both nights it was rather cold out (low 30s), and tonight it is damp.
What should i do?? (btw still no CEL or anything)
