Question exhaust ?

ok .... i know if you get a intake,dp, and main pipe you should get it retuned or what not ... but what about intake,dp and a cat back, cause the cat back wont flow as much as the main pipe ... so is it as crucial (sp?) to get it tuned with a cat back instead of a main pipe

wow what you said is really confusing.. of course if u get a midpipe there will be no restriction and thus creep will be the end of your motor unless you get proper fuel to the engine to compensate for the extra boost

keep the boost at 10 psi and you will not have a problem. you can change out the wastegate pill or get a boost controller. the boost must be limited to 10 psi. search and you will find a lot of info on this subject under the 10 psi rule.

1. Don't get a midpipe.
2. Keep boost to 10 psi with a boost controller if necessary.

Get the midpipe, you will notice a big difference of power, BUT in order to not get creep get a boost controller and port the wastegate(easy) and you should be Fine.

Bad advice.

A boost controller will *not* help control boost creep.

Porting the wastegate requires removing your turbos, and most shops charge around $600-700 for the whole job, if that gives you any idea of the time involved.

It's not hard to remove the turbos, anyone would be able to that who knows the basics. And it is hard to contol the creep but these mods will help.

Removing the tubos

You only have to remove the precat or dp and like 12bolts and the hoses and take the twins right off, it is time consuming but dosent take that long about a 1day's work for the removal, porting, and back in.

What!!! You make it sound like a walk in the park. This begs the question: Have you ever removed your turbos? It's a little more than 12 bolts.

I don't know how to make this any more crystal-clear:

boost controllers do not help combat boost creep

It's a mechanically controlled condition. You either need to introduce more exhaust backpressure, or get a bigger wastegate.

Well it does depend on the person and his experience but it really shouldnt take more than a day's work.

The stock twin turbos have an internal wastegate. It's part of the mechanism that the turbos are attached to. You can't just replace the wastegate.
