Its a shame they are running out, i think we have the last of them here in stock, i dont think anyone can get hold of them anymore.
44psi

what map sensor - 5 bar?
bet that was lively and how the fook do you map it when its like that? big balls imho lol.
Im hoping to run mine fairly hard but want it to be reliable, i hoping to hold 2 bar to the limiter and nice spike in the mid range
