Re: 13t boost questions
In that case cant I just adjust my wastegate linkage to hold more boost?

Re: 13t boost questions
1998. 1997 is the last year for using a manual boost controller without an ECU tune.

Re: 13t boost questions
Cool! Good looking V70. You can adjust the wastegate for different behavior. What it does is change the RPM range when boost is available, not the amount of boost. It's a misconception that it'll increase or decrease boost pressure itself.

Re: 13t boost questions
Confused.. the attached article says that adjusting the wastegate will increase or decrease the amount of available boost which is what I thought it would do. The wastegate keeps the turbo from overboosting via spring/mechanical pressure against waste gate door??

Re: 13t boost questions
If it was that easy, the ECU tuning companies would be out of business.

Re: 13t boost questions
Perhaps this is just my ignorance, but when I turn up my wastegate pressure I get an overboost code and my computer compensates by cutting fuel my tuner guy says that's what he tunes for.. he adjusts the computer to accept a higher value.. man now I'm really confused! Again pardon my ignorance I've only been into volvos for a few years and just recently started nodding them
