[QUOTE="ctgreddy, post: 12202123, member: 122280"] my buddy(last owner of my car) put a 2.8 pulley, midpipe, catback, cai, and tune on the car with no fuel or maf upgrades and it was fine. when I originally did my ported blower i had the original mods to the car plus ported blower/plenum/tb and stepped down to the 2.76 and the fuel was at 98% duty cycle, not sure about the maf because i added a mafia right away just to be safe, i have now put on a bap to lower the duty cycle. but i wouldn't worry about the fuel cutting it unless one of your pumps is weak. the maf SHOULD be a ok but like stated above every car is different. a dyno tune isnt really necessary either at that point,imo, while you'll be leaving hp on the table with a mail order/general tune it will be fine. however i would highly recommend atleast temporarily hooking up a wideband to it just to make sure it's in a good afr range if not going the dyno tune route. my car with the mods in the sig has a mail order tune.
