My 98 LS1 Camaro "I was told" was tuned for a 175 shot. When I bought it it had motor plugs in it I will probably only spray a 150... "But knowing me I will probably go bigger at least the 175" Lol which plugs should I run? How will they act on motor and what should I gap at? Thanks

Normally you want to go 1 step cooler per 100hp. I would put 7's in it and roll with it. Gap at .030 to .032.

I run BR7's and they work just as good as any other plug on motor. It's all in the tune

Our car runs fine on a #10 plug. Sbe, 10:1 compression. Like said, a good tuner can get it to idle cruise fine on a colder plug. Our runs fine on a motor pass up to a Br8 ,but, anything colder will break up some above 6000 rpm. It will idle and cruise fine though on a 9 or 10. Sounds like a 7 is what you need for that jet though.

I have a couple boxes of B8EF in the garage, but I have never used them. Even with a 81N jet tune, my BR7s look perfect with no signs of excess heat. This is in a 10.8:1 LQ9.

What kind of gas are y'all running?

Gettin' it done on 93 for me. Pulling 8 degrees and keeping the tune lean and clean.

93 octane only here. no race gas.

I went with BR7EF gapped at 30-32 and I will also be on 93 pump. Does ethanol gas affect performance?
