Well we have boost now. Started slowly at 1.4 bar to make sure all was well, then up to 1.6 peak. Spool is really fast, like k03 fast, but holds so much more at the top. There is more in it and currently running boost 8, fuel 9 and timing 6. Hot day today and maf figures were lower than I expected so I will put my spare maf on. Fuel pressure is spot on and no dips around the 5k mark.
Happy, but I could be happier.
