could do that, would expect to see 400 if lucky.. although I could be wrong and it might make more.. trying to think of a similar car.. did an sc46 on a tmic on a 2.5 and stuck to lower boost due to the thin liners on 2.5 and was 418bhp iirc.. on standard headers, air box and tmic.

Thanks Simon,

im on 360 at the moment and looking to go 420ish next year,
what would 850 cc injectors and FPR add to the 360 in your opinion?
