voodoo on 23s

im having a problem on my boosted ls-t. i thought my fuel pump went out cuz it stop turning on and changed it but it ended up being a fuse so i put my old 255 walbro in so i didnt get charged and now my car runs fine but when i get into boost there is no power and it acts like its really rich or really lean. i changed the plugs and its still the same. is it possible my gm 4 bar went out? oh also my setup is running on dsm455's, a gm 4 bar map, and a phearable.com chip. if anybody has any other ideas that would be great cuz i wanna get back to ripping gears again.

you check your intercooler piping for leaks? hose blown off maybe? I'd suggest getting a tune as well, those base maps are simply that, a base to start a tune, by no means a substitute.

imma change the cap and maybe the coil and maybe that will work. hopefully its just the coil going out

Needs a bigger turbo...

I said that because no where you've mentioned what turbo you were running. You can run a GT15 turbo at 20 PSI and you will be under 160 WHP, so it won't be fast anyway.

First step in getting good help, is to OFFER useable information about your car.

might be your dizzy, my car was feeling the same kinda sluggish while in boost, switched out my dizzy and wow night and day difference.
