put real fuel in the tank, never mind 93.
sounds like theres a few issues, but im going to say the biggest with your tune was fuel with good fuel maybe you would have been able to run it like it was. start there.

Yes Jeff is cool as hell.. He was tuning on a friends Modified Street car down here at Steele, AL a few weeks ago and he gave me a lot of good tuning tips and took time out of his day to explain a lot of **** to us. Very cool guy.. Got his shirt on right now matter of fact!

then another 150. The motor will last alot longer. Way less strain on the engine. especially from a dig. Good luck with what ever you decide.

too many guys, myself included, have been told its "ok" by "tuners" that running nitrous on top of n/a tuneups is ok.
they are great on the dyno for the few seconds the car is loaded (@ 2800 lbs)
but in real life, the tuneup is way the hell off and runs much slower that it should and eats itself alive.

Looks like its already been said but thats to much timing, gap and spark plug heat range.
If this is a N2O motor get the coldest plugs you can get. Because it doesnt matter what it makes on motor because it will not be ran on motor. Always get the coldest plug you can get. For extra safety.And dont run pump gas.

Can can run a N/A tune as long as you pull timing. The A/F will be fine.

had the c5 vette on the dyno - 402, 11:1,235 tfs,fast 92,wilson direct port,nitrous maximizer 2,stand alone fuel system etc .the question i have is on a 300 shot car made 860 rwhp on a mustang dyno on that pass air fuel crept to the 12.2 range changed fuel jets up 1 size and made 865 car shut off at 6k thanks to the fjo widwband but blew head gasket cyl 5 ! but the bigger problem is it also took out the block and head it was like a torch sliced a hole in both of them has any one seen this on a ls2 engine ,also with a properly tuned engine what is a safe nos level be ? p.s the bottem end is forged and has coated pistons,was thinking it burned the head because the piston coating was stronger than the block . any input would be great

Lots of good advice in this thread. I am going to aggree with these guys. Wrong fuel, to much timming, and need to close the gap up on the plug you have.
Personally I like the 9 would be ok with the correct timming but it would not hurt going to a 10.
