i just had my car flashed with a tune that is setup for my car. (93 rx7 with a turbo'd 2001 ls1, with a 2 bar sd tune) The car had some leaks so we never drove it, today i fixed the leaks and figured id see if i could putt around. as soon as you put the car in gear and start to move (hit the gas pedal), it goes to the extreme lean position (according to my aem w/b) and the car runs like ****. although at an idle. i can sit there and rev the hell out of it no problem. any ideas what could be the problem? im having my tuner come back on sunday to retune the car but would like to see if there is anything i should look for before he gets there..

thanks!
