Default Nitrous Help!
I have 97 A4 Camaro with LTs and full exhaust. I'm running a NX Stage 1 EFI kit and the car seems to surge at higher rpms. I already run the NGk TR6 plugs gap is .045. blended my fuel and run lt4 knock sensor. I think it might need an upgraded coil or opti spark. Any ideas?

how much are you spraying? my experience is that surging can be a good indicator that your jets need adjustment. is it a wet kit?

also do you have good bottle pressure?

walk yourself through all of the basic faq's, i am sure you will come up with the culprit

first off close that huge factory gap you are setting on those plugs should be no more than .35...also are you running wet or dry kit?

What size shot? You could be partially blowing out the spark depending on the size shot you're running. Close your gap a little like lt170chevelle suggested.
