im currently running Tr6 on my TT setup. mine are gapped at .035 now i took it one more step and indexed all my plugs. some say it makes a difference some say it doesnt. Its an old school method that i decided to try out. Take it for what its worth but im making good power on hardly any boost, great idle at 16" with my cam, great throttle response. its a pITA but i think its worth iindexing rings are about 8 bucks

Seems like a big gap, I've been running somewhere between .020-.025, can't remember exactly.

i just put em at 40 ..was reading on tech some of them are at .55 im throwing 2 codes after the ls3 intake swap po171 and 174 too lean i got a retune friday

no issues with blowout with blowout either. the indexing helps as it puts all the electrodes facing the combustion instead of anywhere. however im only 11psi but again i made my power NA then little boost added

hey Quik what water pump do i need..on my ls3 intake swap i cant run the ls3/ls7tb it hits the water pump...i was looking at the ls3 pump but i heard it would need spacers and well the water neck is on the opposite side it may interfere with my belt.

These indexing rings, normal parts house stuff or a Summit/Jegs deal? Might as well do it when I have my heads off and can see and do it easily
