K03 isn't going to hold high boost very long because the increasing speed of the wheel can not be held. The more boost you try to run the quicker it tapers off.


A fmic will help you reduce the amount of power lost when pushing the car hard thru the gears.

 

okay my stock turbo is gay so what the best cheap turbo that bolt on then??? don't wanna waste 500 to get it chip out if my turbo not going hold boost

 

Check the newbie sticky at the top of the B5 page but
I'm going to eventually go with a gtrs which bolts right up to the stock manifold.

 

So the 99+ will hold a few more psi. Can you swap the ecu for an older b5?

 

The GTRS or GT2871r Elim kit, more power and pulls to 7k rpm.
