what to do next

[kanye west]

got a 03 with mid pipe and catback with intake and a tune just got it what do u think hp is at the wheels and what is a good pullie to go with thanx in adv for any help

 

[Posi]

Most will say 2.76 upper. I like the 2.80 upper though. Less heat and almost as much power. Later you can go with a ported blower and a 4lb lower.

MM subframes and Billetflow IRS brace.
Next 2.76 pulley and a good tune.
