Hey guys! Just did some work on my gsx which included installing a boost gauge. It reads 12psi of vacuum at idle, but when i rev to 3k the vacuum goes up to 20. Getting in a couple parts in soon to run a boost leak test. Do you guys think I have a leak or different problem?Thanks!
So I just finished my build on my 98 GSX and its running good but super rich. I just bought the car and found it has a bad head gasket so i pulled the motor and did some mods. Balance shaft elim kit, egr delete, head studs, manley valves, bc valves springs, bc 272 cams, adj cam gears, gates...
