a tune will always make it safer and get more power.

if your not gonna tune you need to run atleast 93 octane. if you dont have 93, then get 91 and some torco, but dont go below that. weve told hyou its not safe and its not afe for a reason. you could probably get away with it, but a $600 tune is a helluva lot cheaper than a new $3000 shortblock

Thanks for that info, I think I'll get the 15 lb bottle then. About how much does it cost to refill a 15 lb bottle???

[Drgnracin72]

most places around here are $3.50 per pound so $3.50x15= $52.50

[Drgnracin72]

and its only gonna get more expensive, and most places ive gotten filled at have all said itll be jumping up again to around $4 per pound. a supercharger is much cheaper in the long run

This is some good info guys! I'll be installing my NX kit in the Bullitt when I get back to Houston and getting a Zex kit for my 3.3L H/C 89' SHO.
