Its complicated, but the main thing is that I get hardly any boost in 1st gear. Not much in 2nd gear. I hit 9-8-10 fade in 3rd gear. I hot 10-8-10 slow fade in 4th gear. I have had this for a while, with still no solution.

 

I'm sorry for not keeping up, but what exactly have you checked and gone through investigating this problem?

 

I've checked for every possible leak. I've also checked all the vaccume hoses. I found one that was split, but fixed it and it showed some improvement, but I still have this issue.

So basically I'm just sure that there are no leaks in the hoses or piping, but that's about it.

 

I didn't see anything in your signature about a downpipe or midpipe so I assume you are running with catalytic converters? If so, have you verified that they aren't clogged?

 

Nope I haven't. I will probably replace the downpipe some time in the next 5 months.

 

Hey I would assume that if indeed you have checked all your vaccum lines.And made sure the check valves are pointing the right way .It's either the intake manifold gasket not seated/sealing properly.Or that damned horrible pre- cat ! Lose that thing fast ,it's nothing but bad news for your ride.
good luck
