Nitrous question
I have the NOS wet system on the 89 IROC.
Bought the system used and just slapped it in there. Well, today I removed the jets and they were BOTH 70's. So then I called N.O.S. and they told me it's supposed to be 70 -Nitrous jet, and 53 for the fuel jet. That's for 150HP.
Here's the question:
How would this affect the performance of the nitrous? It sure didn't seem like 150HP before, maybe that was the whole problem, I dunno.
Thanks!

If you were running a 70 jet for fuel and a 70 for nitrous you would be running way rich. This would definately affect your performance. Go with the recommended jetting and check your plugs. If they look good leave it alone, if not you may to may slight jetting changes.
