My friend has a 00 sunfire 2200 that we're turbo-ing. I'm wondering, if someone from the forum in my area has HP tuners, can one just buy vehicle credits and use it to tune the car? Or does one have to shell out 500$ for the entire suite?

If so, would anyone in the area be willing to help me?

 

if someone in your area is willing then yes you'd need to at a minimum shell out the credits for the vehicle which would probably be (2) credits @ $49.99 each...I would also recommend some sort of compensation for the use of the hardware, software, laptop, etc. Considering it sounds like a complex combo I could only assume it would take you 2-3 charges of the laptop & several hours of time.
