i have a cosworth that i recently brought & it has 300bhp with graphs to prove & it goes like 300bhp

the thing is it didnt have a boost gauge in it so i rigged up a old 1 to check the boost & its boosting about 22psi on a t34 which is ok but it has standard yellow injectors.

are these ok at this boost etc..??? as all my others have had greens fitted at this psi

i removed ecu & inspected chip & its a superchips chip in it but dont know the spec of it.

carts spec is
chip ecu
3 bar map (i think)
samcos
k&n conefiler
t34
22psi

should be a healthy 300 horses

but am wanting more so was thinking if the chips ok for greens then fitting:

greens
full s/s exhaust
4x4 or rs500 cooler

should see about 330+ then???

of if i have 2 get a new chip then go for:

new chip???
greys
s/s exhaust & rs500 intercooler

chould see 360+????????
