car runs really rough on cold start for about a min seems as the engine temps go up its fine. i dont know if it has to do with cold plugs or waht but it feels like its missing when i go to take off. it is fine once im above about 1200 rpm. im also wondering if it could be fueling related. any ideas?

Are you saying you took -all- enrichment out of OLFA?
Or just mellowed it out? You probably do need some
cold start enrichment, just nowhere near as much as
the stock table plus cam idle MAP would put on you.
I'd check the colder (or bugger cold, depending on the
weather's influence) ECT columns and mess them up or
down a fraction, see what helps (leaner or richer,
temp-local).

What mods require you to run TR6's. In my experience they are way to cold for normal NA applications. I had a guy come to me with hard starting problems and a "cam" sounding idle. He had 10k or so on TR6's. I had him switch to 55's and it solved the problem.
