Ty ran o.k. till today. No boost after 5 lbs. and the engine begins to hesitate (miss) if boost is applied. Anything before the 5lbs the car runs great. What's the problem? Any help would greatly be appreciated[/b]

Haven't had a chance to pull up any codes yet. Just trying to find out if anybody else had similar problem and what they did to solve it. Ignition system was checked and everything is functional in that department. What typically can cause this to happen? Anyone out there with past experiences are more than welcomed to reply. Thanks in advance

"Checking" the ignition system is not the answer here IMHO. It is almost impossible to tell anything other than very obvious damage by just checking things out.
Doing an insulation breakdown test on plug wires is not common, yet one of the only ways to determine if your wires are good. Installing a set of new wires is the only way to really "check" that block in the real world IMHO.
Cap and rotor should be replaced with a quality brand like "Conrad", and a set of fresh stock spec plugs, either the ACCR42TS, or the NGK UR5s, should be installed. Once you have some ignition parts in there that are know to work well in our application, then addressing other possible malfuntions is in order. However, I will bet that once you get the right components in the ignition that you will not likely need to troubleshoot further. What parts currently make up your ignition?
Again, I highly recommend redoing your ignition.....

Should that not cure your problems, then go to fuel. Replace your fuel filter and check fuel system pressure, at idle and full boost.
Ignition, then fuel..
Hope that helps,
