Recently installed +40s, 3 bar map, and FWDP TIII Stage 3 computer. I know Cindy said the stock turbo can't keep up with the 18psi advertised on the calibration. I figured I'd put a MBC on it about 15 and call it a day for now, but I'm getting erratic readings. This data log is with an MBC cranked all the way down. Either I have a leak in the wastegate diaphram, or something else is limiting the boost. Not sure if it's pulling timing and causing it or the timing reduction is standard as the boost goes up. Anyone have any thoughts? Ask any questions you feel will assist in understanding the log.
Thanks,
