Boost looks low too!
Hey there John Hurdy, it is 21 psi now...normal for GIAC K04-HO tune here in the states. I quit running the DriverMotorsport K04+ tune. It was 25 psi but never beat my 1/4 ET of the GIAC tune and I had to rebuild the engine last year because of rings pinched in the piston grooves. I thought it safer to reduce the boost
My biggest issue is finding the cause of the fuel pressure. GIAC doesn't want to send me an improved stronger tune, having IE connecting rods now, until they see this corrected...and I don't know what to do other than a new hpfp w/internals next.
