manual or auto tranny sprint booster?
I have been reading a few threads for sprint boosters and I have a manual transmission on my x-f. I have been reading that the manual sprint booster is more agressive and some prefer to put the auto tranny sprint booster instead. Is there such a difference? What does it change form one to another?(auto-manual) Is it too agressive to the point that it is hard to drive in traffic when you have to clutch and un-clutch? Has anyone ever tried the difference?
Thanks!
