Actually as I found out the hard way the canned DHP tuned PCM's you buy for $100 only work part of the time. Some cars it's an improvement and sometimes it causes more problems. In my case more problems as in my sig.

I've had problems getting in contact with DHP to resolve some issues so I'm going to go with HP Tuners.

 

yea your right ima go with hp too, 500 bucks though better be worth it, ima get a case learn, and see what happens from there
