Running strange in high gear?

[TitaniumTT]

Dude, you can't properly diagnose a piss-poor running car until you know that everything is working properly. You're chasing your tail when the biscuit is laying on the floor in front of you.

My exhaust gasket is blown out, why can't my turbo spool. The car chokes itself and the secondaries aren't working right. You've diagnosed the problems, now fix them. If it's still having the same issues, than it's time to look elsewhere. But why look elsewhere when two causes for the problems you're having are known and staring you in the face?

Fix the exhaust leak, rip out the thermowax system and the secondary butterflies. These are two things that are wrong. Wrong things make cars not run right. Fix the wrong things, if it's still wrong, then start looking for other things that aren't right.
