Playing with LFS-tune, changing power outputs and drivetrain to any value seem to make handling alot worse

IE: XR GT, I DROP engine size and it goes slower yet in the BLP Track I cant make it around the first turn going over 40MPH, i can usually hit it over 50MPH....

what gives? LFStune make the car inevitable heavier ?

I wouldn't bother changing the drive train unless you only want to go fast in a straight line. Each time you change it LFS automagically defaults it to Viscous which sucks, and although you select locked or lsd it still uses the viscous pack (or that's my conclusion).
