At GM Parts Direct the kit is $455 + shipping, then what the dealer would charge to reflash your computer, $200 to $300 more total $655 to $755. OK a little more then 1/2 the price. GM's kit gives you 30 more HP. That's engine HP. I got 38.5 WHP. That is to the wheels and you lose any where from 15% to 20% from the engine to the ground. I have an Auto, so it's around 20% loss. So that comes to 46.2HP on the engine compared to Gm's 30HP.
Plus will GM's kit give you full 21 PSI in all gears (1st thur 5th.) and boost faster. From the line, floored the boost will jump to 21 in a blink of an eye and does not drop below 19 as it goes through the gears.
I have the Dyno sheet, just don't know how to add it to this page.
