It all matters if you really think a chip should be your best investment, or your first choice in mods. The do quite a bit if you have mods done to the car aka supercharged, some bolt-ons, great way to tune the car to your mods. Pretty much stock car you won't notice THAT much. If your just going for a firmer shift with the transmission and thats all you really want to get out of your chip is that, its much cheaper to just perform the JMOD, better to physicaly change the fluid flow then just up the line pressure. I guess it all depends in the end what you want out of your chip.
