Just got a 89 Gtc coupe and it's running too rich, idles too high and barely starts (cranks forever and stalls).
Specs
2.5 T1
287 G head
A413
+40 injectors
Accufab FPR
Stage 5? Fwd smec
3 bar map?
Walbro 255 pump
Side exit straight pipe exhaust
Srt intercooler
Garret Turbo (was told its a Super 70 but it looks like a standard T2)
Has a AF and boost gauge idle is pegged rich...
Car came with a vacuum block so far hooked up Fpr,Map,Bov,wastegate,boost gauge.
What's the correct ignition timing and fuel pressure to run on this?
I have a fuel pressure gauge and the AF gauge seems to work.
