i dunno, i have yet to hit 18 anymore, i dont spike higher than 15psi. and thats onlyin first gear.

 

Come to Columbus again sometime and we'll meet up and have a looksee if you dont figure anything out.

 

i think thiscould be the problem.. how positive are they that you previously had revo

 

not sure they just said i might have had it on.

alright onepoint8tee, ill pm ya the next time i head down. thanks

 

i think i know my problem, im thinkin since my car has 135k on the odometer the turbo is a bit wore out from never being rebuilt. i might just get a newer k03 or rebuild mine

 

My K03 has 165k miles and holds 15. If you are looking for 15 at redline you can forget about a K03. They run out of steam above 5000 rpm.

Have you checked your diverter valve?

 

MINE wont hold over 15 psi over 5k..I changed my dv to the forge 007, and i still dont hold all the boost until redline.

 

I think it could be the forge 007....I have heard a lot of people having trouble out of them

 

AudiTurbo,
Your problem existed before installing the 007 and you are pointing to it as the cause? Or am I misunderstanding something?

Exhausts do indeed have a dramatic effect on turbo cars.

A spike followed by gradually dropping boost is normal on a stock turbo'ed 1.8t. that being said your boost still seems low. Try the test I posted in your other thread to determine if the valve is sealing, if it passes might I suggest you looking at your N75? Or your turbo may be on its way out.
