Thumbs up to Ion from Madz28.com. The guy answered all my PM's and emails promptly concerning any questions I had no matter how newb they were. For those of you thinking about getting this done, I just installed my computer yesterday and it was the best thing I coulda done for my car. The installation couldn't have been easier. I'm so glad I got rid of my HPP3. What a piece of crap that was. I can def. feel the difference in HP in Ion's tune and best part about it, I dont get any more dumb EGR codes. My car used to surge at low rpm after I converted to a higher stall but Ion said he'd try some stuff out and whatever he did, it fixed the problem completely. So, thumbs way up for this guy.
