100 shot & tune?

Ok, i'm thinking i might just get me one of those new sniper EFI kits, just wondering where i should have my total timing set at & WOT A/F for 100 shot, will 32* total & 12.8 be fine on 91 octane, because thats all i can get around here, & will the NGK 3403s be ok, i would run alittle unleaded race fuel if needed, but i was told it'll mess with the 02s, is this true?

NGK TR-6 is the plug you'll want..If its tuned properly, you shouldn't need the race fuel. But if you want to, the UNLEADED fuel is fine. The LEADED fuel will mess up the o2's.

If you're running a wet kit, and only 100 horse power, you don't need any tuning, just higher octane. Premium pump fuel MAY be sufficient. I've personally used a 150 shot of NX with 92 octane on my stock LT1 Corvette years ago without any issues; I only used 100 octane unleaded when I increased the jetting to 175 horse power, and the tune remained unchanged.

Camaro, stock everything except CAI & gutted cat thats it, stock rear, stock rims, street tires, i was so impressed with his times & MPH, he said he is still running off the stock fuel pump & no issues.

Everybodys different, and has their opinions. So, it may depend on who you talk to and trust. I wouldn't run a stock pump, and I would mess with the tune..Otherwise you'll be running that HIGH priced octane on the street, just wasting it, when you dont really need it.
