thanks to everyone for all their info on this thread. i got my tuned running like a rolex... still needs about 10 deg cooler i think, but i went 10minutes last night in the main with a little left over... smooth power, no lean bog, no rich low-end (got rid of that surge when i let off at the end of the straight) and it idles on the box long enough to smoke half a cigarette without loading up at all.
