Tuning with a 75 shot
 

Other than better fuel supply and better (colder) plugs, do you really need to do any other tuning (ECU wise) for a 75 shot or will stock ECU settings be ok?

As long as it's a wet shot you should be fine.

The ecu is not even aware that nitrous is used because it is run in open loop mode. There are no sensors involved. You will be fine with out a upgraded fuel pump. It never hurts though.

Get the fuel pump. Eclipse stocker will do.

So I upgraded to nitrous (Instead of turbo) I was told it was a 50-70 wet shot. I tried it and the rpm jump caught me slipping and let go because of sudden rpm jump. Through out the run I sprayed and I did feel a really big pull, but after my check engine came on.....my oem exhast manifold is crack, is it possible that the nitrous some how damaged the cat?? Also now my tibby sounds beast, like if I had stage 3 cams lolz.

if its loping you prolly fried your plugs bud.

You were TOLD it was a 50-70 shot? You should KNOW this info before doing something like that.

You'll also need a clutch for 50+hp. My stocker slipped at a 60 shot.

No worries on clutch, am running stage 3 smile.gif and no the plugs when removed were fine and in good condition, currently running ngk v power now. IDK exactly what happened but am under suspicion that the nitrous blew up my manifold and or o2 sensor. The cars leak got worse and now it really smells sad.gif

If it's a stock exhaust manifold, remove the nitrous stuff and go to a dealer, and they should replace the manifold free (if it is welded to the cat)

Yes it is the exhaust manifold welded to the cat. What exactly do I tell them? recall for a 1998???
