Well confirmed it with the boys today unable to get a nistune for s1 stag, s1 r33 all good but stagea runs different wiring plug so can not use the vg30 comp as they do in early 33 to get past tune probs oh well looks like im going down the old microtec road. wired enough of them in by now should be able to do with my eyes shut but really didnt want hassle, prob best in long run with engine set up ideas on the board for the future
