My TT has been in safety boost since ive owned it(about 2-3 years), but compression has always been good, and ive done alot of work to it(mostly maintenance).
Earlier this year I replaced the turbos, manifolds, all vacuum hosing routed for a quick EBC install once I get it, CZP ECU upgrade + boost jets, deleted the stock boost solenoids and several other components, and replaced the knock sensor with one from a V8 Titan + a z32 knock subharness
- was at Z shop picking up cats for emissions and thats all he had but said it would work...Last night I decided to try the 1M Ohm Resistor for my code 34 (only cuz I don't think im detonating)
Verified Codes:
1. After installing the resistor
2. Starting the car
3. 2nd gear pulled to 4k rpm
4. A quick highway drive pulling over 5k rpm a couple times.
Still had code 55, but the few times I boosted I couldn't get past 7psi the 2nd mark above 0 if im correct?
Usually it peaks just below the 2nd mark above 0(safety boost), so it boosted maybe 1psi more than usual. Im guessing this is because I have:
Vacuum + Boost Jets - Boost Solenoid(s) =
7psi max wastegate pressure - could upgrading wastegates be an alternative route than installing an EBC to increase boost?
- or bigger turbos utilizing stronger wastegates?
1. Does anyone know about how much power is lost in safety boost compared to stock?
2. Does safety boost reduce power gains from mods?
e.x. intake/down pipes/catback/etc gain ~10-20hp each, but running code 34 only produces ~5-10hp each
