I've got a healthy compression wise 20vt, gt28rsr, tip pipe and large bell mount air filter with feed, aftermarket exhaust/downpipe, fuel pump mod and walbro 255, downpipe/decat, evo intercooler and apexi avcr.

Looking to run 1.2 bar on 99 ron, it's been tuned before by flea wondering what power figures I should realistically see?

It's very lean in 14s low down from 2000 to 4000 then richens up at uptop to 12.4 which is still too lean. I'll check fuel pump voltage but I suspect maf sensor.

Thanks
