Car is hesitating now!!!!!!

[DaOnE51T]

A few days ago I bought a 1992 Laser RS Turbo AWD. I bought the car with a 3in downpipe, high flow cat, and Thermal Research and Development. The car came with a turbo XS MBC and boost gauge. Yesterday I change the oil to 10w 30 Mobile and NGKR BPR6ES spark plugs(gapped 35). The car was running like a champ boosting 15psi. Today I cut up the air can(stock air filter) and removed the silencer. Now it is hesitating at around 4,000-4,500RPM's during WOT but when you slowly punch it is fine. I have been reading the forums and thought I might have the so called "fuel cut". So I removed the lower honeycomb thinking it would solve it but it did'nt. Has anyone ever experienced this? If so what was the solution?

i know it doesnt sound appealing, but try and turn down the boost a little (this may help) .... upgrade your fuel pump and rewire www.vfaq.com (you can use this site for all sorts of stuff)

Good Luck

You may need to adjust your ignition timing. Just an idea.
Seems like since it started hesitating after you cut your airbox, it sounds like a air/fuel problem. You may need to hack your MAF to richen it up a bit.
