its just a stright map, no box.
It gets about 20% better in the first 100 miles yes.
had it RR'd a few times and ive had 260bhp 320 torque. but i have TBE, intake and FMIC.
its very torquey at low revs and peak boosts at around 22psi (ive seen 26psi
) and then tails off around the 5k.
Theres also a small flat spot in mine at high revs in 4th gear but then pics back up. I think this may be a faults somewhere with my car though.
i can vouch for Joes car being a FAST car. Its one of the quickest K03 cars ive seen pass me! maybe thats joes right foot, but its real quick, even past police vans! haha!
LOL, i didnt even see that van!!
