Drive the car?

Why'd you buy it? Trying to fix a problem?

Parallel or stand alone MS install?

I've never used the TPS for anything except launch control?

Standalone install.

Do I not need to adjust anything in AE? I have no graph at all.

You should be using MAP based AE.

Quantify that statement please?

I used TPS AE on my MS1 for 4+ years.

I use 80%TPS AE on my MS2 (it's blended with MAP based)

MAP changes are faster and greater than TPS changes.

Depending on the dynamics of the rest of the system and how its being driven of course, a small change in TP can cause a large and fast change in MAP. ie tip in from 4th gear cruise while in vacuum at 4krpm, doesn't take much throttle to just to 5psi boost. Seems easier to account for this via MAP based AE.

That's the tuning theory I subscribe to anyway....
