Hi laboy561...

"Turning up the turbo" is a misnomer. There is very little that can (or should) be done in a street car, short of changing the ECU, that will increase maximum turbo boost.

What is being referred to is adjusting the rod that goes from the actuator to the wastegate itself. That adjustment is usually done in reference to its stock position... "turning it up two notches" means shortening the rod by two clockwise turns of the attachment.

What you have to understand, is that the wastegate controls the flow of exhaust gases through the turbine that spins the compressor... it does not actually limit manifold pressure directly. The opening of the wastegate at various boost pressures is controlled by the ECU, not by the above mentioned rod. Shortening the rod only changes the "base line" adjustment of the wastegate. What that does, however, is spool up the turbo earlier on, resulting in boost coming up quicker at lower revs, with less perceived turbo lag immediately off idle.

You should carefully read the following site... it's the best I've ever found:

But I agree with "KlausC" 100%... these cars have plenty of power. Not that I'm not a "power junkie"... I say the more the better (within reason). It's not just a question of power, but a question of the balance between that power, drivability, and parts longevity. Calling for high power at low speeds puts maximum stress on every critical component, but mostly the transmission. The soft throttle tip-in and minimal turbo lag of 850's combine to encourage gentler applications of full power. These are lovely, well mannered, stealthily fast, good handling cars... not dragsters. Perhaps you should leave it well enough alone.

The greatest impact you can have on throttle response without doing anything else, is to be sure that you use a good air filter, and change it regularly.

By the way, congratulations... you have good tires.

Good luck
