Engine running rich, bucks when coasting/slowing down, lack of lowend power post-swap

[ledzep2acdc]

Got an 88 BB Mark VII and swapped in a ford crate rated @ 340 hp with GT-40 aluminum heads, E303 cam, polished cobra intake manifold, 24# injectors, converted to MAF 70 mm and A9P computer with a BBK CAI kit with bigger headers. problem is, this thing has lost a good deal of low end power(i know, its a heavy @$$ car but the stock engine had more low-end power!), its running rich (either that or im burnin anti-freeze god no), and it bucks like a mother when im slowing down or coasting. I put in a MSD coil to see if i could get a better spark but didnt help the richness. I dunno bout you but I cant even burn out (no posi yet) which i found pathetic with all ive put into it. I also had a cat-back exhaust put on a year ago. Guy who I had give it a final tuneup recommended an MSD ignition box which I planned on doing anyway but not yet, especially after what ive done over the summer: im broke as hell lol.

any ideas!?!?

thanks

Maybe start off by pulling the codes. If it's running as bad as you say, its probably going to throw some.

It's actually kinda nifty how the computer can tell you what's wrong

+1 on pulling codes first. my car use to want to sputter and die when i came to a stop and it ended up being a bad egr valve. don't know if thats your problem, but might be something to check

is your mass air meter calibrated for the 24# injectors?

is your mass air meter calibrated for the 24# injectors?

Please tell us more about your MAF/MAS meter...

Can you post the part numbers on the sensor?
