Neither :wink:
Knock would be my main consideration
EGTs are affected precious little by W.I. (strange but true!)
IATs are affected only a tiny bit - depends mainly on the location of the nozzle, post-ic temps and methanol content
Emergence of knock's ugly head is what WI is meant to fight best. |
On the subject of knock, i been having a few issues with my boost control solenoid virtully since i took the intercooler off and the car has only been running 12-15 psi when it should run 18psi, i havent worried about it until the new 3-port boost solenoid arrives(which is sometime away) and a re-tune . But today i put on my old manual bleed valve in a set the boost to 17psi and the once the revs got around 4500 WOT full Boost the knocklink would light up like a christmas tree but i backed out of it before i got the red light up, this is scary stuff :shock: :shock: so either my WI isn't working or bad fuel or i just can't run anywhere near the same tune as before with the intercooler??
