My Dodge Charger RT (for drag races) used to hit about 160mph in 3rd gear before I added more upgrades to it. Now I have a 4th gear, but as soon as I shift to it, the car loses revs and only lets me rev it to about half way. Also, the car is only maxing 150-160mph per race now, whereas before I could do 180+ with NOS.

How do I fix it?

Done that and managed to fix it, thanks. However, I've got another problem now. D:

I bought a Toyota Supra (as I heard they were the best/one of the best drag cars). I've managed to tune the engine and drivetrain so it's perfect now, at 833bhp on a 2nd stage engine (can't afford 3rd yet). When I accelerate, I can pull wheelies and keep it there until I hit 4th/5th, but the problem I'm having with it is that it has a tendency to veer off to the left or the right occasionally. What can I change that will stop it from doing this? I'm definitely not toughing the analogue/d pad so it's not me - it's the car.
