ok first problem....this morning, got into my car, let the engine warm up like always, started driving it....got on it a few minutes later and my boost gauge was reading 25psi on a stock t25 with no boost controller...it's never done that before...it usually reads 12 - 15MAX.....also i have a question about my friends GSX...last night when he started up his car (which took a good 5min to start) there was a horrible loud knocking sound. i mean this knock was LOUD. so he drove it for a bit...after a good 20min of running it the knock was just getting worse and he noticed his temperature gauge was on H...so he stopped...popped the hood and his exhaust manifold was glowing red. i had to take a picture of it lol... take a look at it...
