How much hp and tq would underdrive pullies and throttle body gain to the wheels? Ik they are advertised as a decent amount but is it actually true. thanks.

Supercharged cars can and do run the stock TB, you can see some gains from it but not much, UDP's are good for a couple. Put together you're talking 10-15 HP. However a TB and UDP's aren't cheap unless you can score a good deal.

if u are looking for horsepower and torque gaines thoughs arent the bigest gaines, look into headers, intake manifold, depending on how much ure looking to spend, another thing if ure looking to gain power no offence but ure exhaust setup is stealing power from ure engine because u need backpressure witch u really lose alot with no mufflers and no cats, i would say get a set of mufflers with the tunner u got u should feel a difference. if u want any more advice or have any questions shoot me a pm and i can explain things in more details
