When driving the car I am only seeing 7 to 10 max boost at WOT. The car will start to sputter at around 4K. When on the highway in 5th at 70mph if I floor it it goes REALLY slow with about 3 to 4 lbs of boost.

The car ran very strong when I first bought it. Seemed a little faster than my 95 that dyno'ed at 270rwhp. Then I had a surging bucking issue. Replaced DIS and I found out the MAF was on all the way. It went away. Then I had coupler issues. It also has a custom raised top and the coupling started blowing of at WOT. Scared the crap out of me the first time it went BOOM! Fixed the issue and now I have loss of power. I put it on a smoker no leaks.
Have new plugs that I need to put on with new wires.
I have new MP springs, seems like it might be slipping still. Those tensioners were clocked and I was wondering if the springs or the tensioner wasn't working properly. Switched tensioners from my 90 and same issue.
From reading I was looking at and checked
IC leaks
Tensioner
SC fluid level
new JS to SC belt, JS to crank belt.
Have shorter belt for JS to SC. The belt is tight.
The accessory belt is not so tight and needs to be replaced. Have AC delete so the stock belt I bought won't work need to find the right size. Can this cause slipping cause a surge at the top end?
Aby suggestions?
Gonna go down soon and see Mike Puckett maybe he will see something.
