Run a safe 18 psi Paul until you get it setup properly, get it live mapped mate, you will not look back (27-28psi spike to 5000revs then drops to 24 and holds till 6000rpm and then tails off slowly for 22psi to the limiter to prevent blowing the engine .)


Get the 500 cooler on there too, you can pick them up for £200 2nd hand

And rolling roads aint proof
