Did my own "Stage 1" tune and Im just guestimating HP from the formula MAF/.8 . Highest maf reading is 180. Is this the most that can be extracted from a completely bone stock 1.8T? Would a KO4 bring me to 250-260? Max boost is 18-19(21 psi peak) tapering to 10 at redline. Also, I can't find anything anywhere on what combined timing should be.(boost PSI+timing) Right now im at around 23-25. I can provide a log if needed.
