tuning software
You cant go wrong with either one, we sell and use both everyday. Both have there pro's and con's just like anything else. We do sell more HPT setups vs EFI. HPT is hard to beat for gas tuning and new vehicle support. Its very cost effective for someone starting out, it also has a HUGE vehicle supported list including alot of other brands besides just GM. I suggest downloading both of them and looking at them for yourself to see which one you like the look and feel of. Free to give us a call if you have any questions about either one, be glad to help.
They are a waste of money. You spend almost the full cost of a real tuning system for a couple of minor functions. It would be like spending $4.99 for a French fry instead of $5.00 for a meal.
