Just bought a new tuner with 4:10's and underdrive pulleys. I am thinking around 30 hp I hope? What you guys think.

Hoping for a little too much. The UDP's will give you about 5 to the wheels and if you are going to an aftermarket tune from the stock one you should pick up 15 or so. But the gears will actually lower your peak HP. They make it WAY more fun to drive, but doesn't look as good on a dyno. Good choice on the gears.

yea gears dont add/remove hp/tq they just change the rate at which the rpms climb (turns the rear wheels faster)

UDP with no tune should get you 7-8rwhp/tq~
