staying tuned right in florida

[blewbyu]

does anyone in florida have a hard time kepping thier car tuned right? i'll go out and tune my car one night and it will run pretty good, then the next night its kinda humid and it runs fat and sluggish. Is this normal? My car was not tempermental like this before my upgrades.

I would say that the manual boost controller could have something to do with that. With changes in atmospheric pressure, sometimes boost is changed slightly. I live in lower AL, and when it gets really humid my car feels a little quicker (dense air combusts better than thin). I would say that yes, it is normal as long as the changes in performance are minimal.
