so far i have a: stage 2 with 2.7 pulley, 60 #injectors, wideband guage, aeroforce gauge, injen cai, stiffys torque damper, lowering springs, and a piggy back ecu.. what kind of gains will i see if i get it hptuned?

 

How has your car not blown up yet? as far as I know, non of the so-calles piggy back units can control larger than the 42lb injectors... and you will see large gains,

 

the piggy back insant instaled yet, wasn't sure if i was going to install it or not, i think im just going to sell it more then likely

 

piggy back? what do you speak of

 

That's a crazy setup my friend. I would get HPTuned so you don't go boom nevermind the gains. The gains will be there but the reliability you can get from a good AFR and no knock outweighs the gains of maybe 10hp depending on how agressive you go.
