Plug Gap
Hi, I have 2004 silverado 1500 with a 4.8, intercooled kb kit, and s475 which is almost ready to go to the dyno to get tuned. I have br7ef's in it which I gapped about .032. After reading a bit more, I almost think I should take them out and narrow up the gap a bit. Would just like some opinions. Max boost will be about 15 lbs.
Thanks
Thanks

Man that's gonna be a beast on your hands with your turbo selection. I ended up not liking my br7ef plug because of the way they acted at idle. And gas mileage went down. So I put tr6s back in it gapped at .028 and with the meth that controlled all my spark issues under boost

And as for turbo selection, I don't like the thought of backpressure robbing power. You don't see too many T6 4.8's running around, lol. Thanks for the replies!
