finished installing h/c and I started it and it idled great, but the third start after a couple of adjustments (tightening header bolts, adjusting coolant and oil levels) the car would continually die. I was wondering if it is just the tune, since the cam is slightly larger??

large? no it is just a tad over stock

my car did the same thing with the MS3 before tune, i wouldn't worry about it at all, just tune it

drill a larger hole in the throttle body, this is common and easily fixed just dont go too big.

Do not do that before you tune, do that as a last resort. If it is just a matter of driving to the tuner, just open the TB blade screw a bit to get you going. Do not go WOT. Just part throttle to the tuner.

you should not have to drill the TB with a stock cube motor, you only do that after the tune if the IAC motor still can't bring on enough air at idle.

I'm assuming it was running off the default for the first couple of starts.....that is good news, other than a smoking header (coolant spill), exhaust leak and tune....I'm ready to roll.

Surely its just that its not tuned, you are probably over worrying that something is wrong, start it from a cold start and let it idle till it gets to operating temperature, that will help it learn the new idle and help it till you get the tune.

Drilling a hole in the TB... hell that's some great advise..

I'll just adjust the throttle body so that it is open slightly, until I get it tunned....

LSWNDR, what are you running for an intake manifold etc? very nice numbers.

LSWNDR

stock Ls6, Ported throttle body. I'm about to get a 92/92 Fast, Pro Charger, and a SixSpeedsInc. STG 3 + Transmission upgrade. Last weekend i raced a 10.98 03 cobra that my friends seen run at pinks STL with a automatic manual valve body on the street from a 40 roll in 3rd gear and we were door to door. He would prolly murder me from a dig lol he hooks like glue but he ***** when my LSWNDR pulls next to him on at about 65 lol.

I'm having problems getting my car tuned as well guys i just can't figure out the idoling up because i have the opposite problem. Hope you have a good tuner whats the LSA on you cam? Mine is a 110-LSA and a tech sponsor told me it's a bitch tuning

I went with the 112-Lobe separation. But I heard that 111 is standard, at least that is what TSP told me.
