thanks guys. i just installed the cobb stage 1 aggressive (since i have 93 octane) and have my wagner FMIC to install on thursday evening after work.
even with only the stage 1 tune, the car pulls really really hard, so i definitely dont think i will need to go past stage 1+.
i will probably go with an etune because the cost / time involved in going all the way up to plano isnt worth it. i do find it ridiculous there is no protuner in a city as big as houston.....
