Hi,
I hit 21 PSI today. Check light went on.
This really scares me. DTK 62mm sc pulley, tighed1īs DIY wrap kit and gatorback belt. DTK tune and TCU, rev limiter 6700.
Didn`t expect boost pressure that high.
Fortunately we have 102 octane pump gas here in Germany (about 95 US equivalent).
What do you guys think is a safe AFR at this level on 95 pump gas and what not :-) ? Can the engine (rods, bearings) take that level of boost for a long time?
I probabely have to change SC pulley back to 65 mm. Very soon.
Thanks
Steven
