I was thinking of putting a TNT kit on my L98. They have a kit that is adjustable from 100-250hp. They say they rate thier stuff at the wheels. I have the rings gapped for a 150 shot. Read my sig for the rest. I think it will go mid tens on the bottle, if not faster.
Next question. I have a digital 6 ignition. Can I use the retard feature with the 730 ecm, or will I have to take timing out of the EEPROM?

 

My buddy has a 91 firebird. Pretty much stock except for exhaust and gears. On a 150 shot of NOS, went from a 14.05 to a 12.20 on a TNT kit. On my 91 Z28 I went from a 14.24 to a 12.64 on a NOS plate kit. Although my trans was slipping a little in third gear. I had a very low mile an hour (103)

 

I was looking at the specs on your car. Just so you wont freak out. Watch your RPM on nitrous, with a 4000 stall on it will stall higher on the spray. Might be kind of high. On my car, all used was a 2800, worked great.
