i was in dannys black escos when i had it and it was nms mapped and it was quick.... had low compression and my car goes better than that with a t34.63

but my cossie has
gt35/ external waste gate screamer ect reyland manifold
autronic sm4
long studded 200 block
forged pistons ( pocketed standard compression)
custom spec cams and head work done by grace engines
83lbs
swedish inlet
and so on

and it just picks up and goes with no problems, it makes full boost around 3700ish rpm and holds to 7500rpm 2.2bar
