Car too lean?

[1990StangGT]

I just installed a new motor (stock longblock), trickflow intake plenum, stock TB, stock MAF, cold air intake, stock headers, mac off-road x pipe with mac 2.5 catback, and mac pulleys. Now my question is it takes off the line like a bat out of hell compared to stock now but feels like it falls off in 2nd around 4500 rpms and gets worse all the way until 4th and it picks back up agian. I have did nothing to the computer so do you think all that air is starving my car of fuel? And what kind of programmer should I buy? And would getting a TB, and MAF even be worth it?

i personally wouldn't waste the money on the programmer & have someone put a good tune in the car on the dyno. just my .02 though

MD does quality stuff & besides www.modularpowerhouse.com they are the only people i would trust with my car.i'm sure that would do fine, but i'd still make the drive to have it tuned properly by someone that knows what they are doing
