Hypertech yea/nay?
I am looking into buying a Hypertech controller for my '03 Sierra w/ 4.8L. I need some extra pulling power and was thinking tuning the ECU would be the best bang for the buck but I wanted to see what everyone thinks about them and if you recommend a different one. Not looking to spend over $300 to do this and I found the Hypertech on sell for $295 online. Let me know, thanks!
