As for the sr being at 100% duty , i was at 83% at 180rwkw . He must be running a t25g at 1.2 bar to get there if the turbo is still stock , that might have something to do with the fuel mixture due to the inefficiencies of the stock turbo at that level . Also the fuel pressure rate rise of the stock regulator will never keep up , next the stock mapping will run at about 10.0 above 4000rpm to protect the engine from detonation . Funny that with a more efficient turbo on the stock ecu the ratio is way leaner throughout the rev range , and the fuel pressure didn't need to be run at such great pressure as before so the injectors where for sure not operating at the same rate as well as more power at 0.8bar . From memory the stock redtop units are only 380 units ? s15 are 440cc ?

Sounds about right. I remember Colin at ricol saying the duty will be a bit higher as its runnin rich as the turbo is at its limit. Its runnin the t25g, well was, kinda shat itself, nice metal grinding soundw come from it now at idle, putting in a new t28 bb in this weekend, should be fun.
I am pretty sure the S15 ones were 440cc
