Now that I have gotten another job hopefuly i will be getting some extra spending cash .. hopefuly ... I was looking at a powertuner for a mod. But I was wondering how hard is a powertuner to use ? because of the looks of DHP's web site I cant tell how they really use this. How is the software set up is it like drop boxes so figure out how to set everything or do you have to do a bunch of calculations to figrue out what numbers to put in each box. I also want to know how useful this product would be for me right now because my GP dosnt have any real mods at the time .. but in the future I plan on doing 1.9 Rockers, SSM90 kit ... (dont know when this will happen) Maybe cam, and a cold air intake, so far i just have a high flow filter and a gutted air box. I am just trying to figure out how all of this works so if a powertuner would be a good mod for me at the time.... or if i should just upgrade my pcm. thanks for the help
