high rpm miss
high rpm miss iv got a miss above 5k. new plugs, wires, cap, rotor, msd coil, known good spark module. the only two things i can think of are either opti or the new plugs need to be gapped closer. fyi the plugs are TR55s and the wires are cheapo o'rielly brand. cap and rotor are acdelco
i dont have a scanner, i have a big exhaust leak so the readings would be off anyway (working on fixing that) but they arent throwing any codes if thats what you mean.
it still needs to be retuned i know that. theres only a basic tune on it right now. idk if he calibrated the knock sensor for headers and roller rockers, idk what he did with the rev limiter, idk if its tuned for a 160 thermo, and i do know the speedometer is off because i never told him i have 4.10s. also i do rev the motor a little higher. 6300-6400 with the new cam, springs, rr, guide plates, ls7 lifters,

Verdad Gallardo ok well i tried putting in TR-6s gapped to 0.050. i think it runs a little better until it hits about 5k and then it goes right back to its same old miss. im thinkin opti, but it was working fine before the cam install. i would rev it to 6k and it ran fine then. im just trying to get the little things out of the way before i try the big thing. not sure what valve float feels like. been told this could be it. i might try resetting my valve lash. any more ideas on what it could be?
