car is acting funny

ok so when the car gets to like 3000 rpm when it should be going into boost it just kinda stutters.......

its a 87coupe w/ 88tc motor la3, just swapped in a t-5 and 2.5 downpipe w/ no cat

Any other problems? does it doing when you free rev, or just under a load? Be a little more descriptive

ok

well the car revs just fine.... when you're driving it stubles real bad.... almost no boost at all...it maybe pulls 1 or 2 psi.... then stutters again till i shift
