I found it was a bit trickier than just winding the fuel out, mine was originally 22psi and screw out 2 turns or so, it was horrible! Mate helped me tune it just buy driving it and watching the boost egt gauges and then making small adjustments, wound the wastegate actuator in a bit the slowly added fuel until it would hit max boost really quick then just small adjustments after that, for every 1 turn on the actautor we did half turn on the fuel.
This knocked 10sec off 0-100 times! (27 sec down to 17sec, no supercar&#128522

Yeah now that I have the clutch sorted I probably should start from scratch again

How fine were you adjustments near the end? Quarter turns? Eighth turns?

1/2 to 1/4.

Mind you stephen, i have to re tune mine again, egt's have dropped by 100 with the new water air intercooler. But will wait until the new motor goes in.

Thats a nice improvement. Maybe you will be able to pull the 1.003 gearing better once it's tweaked a bit more.

I think so, am hating the 1.222 case.
Might look into a few mods for the new engine other than basic fuel amd boost

I agree. It's not as simple as more fuel. On mine a little less was smoother, quieter, better over all.
