You wont have to switch ecms or do the driver mod to run the 60's. fullthrottlespeed.com has high z 60lb injectors that work with the stock ecm no driver mods needed. Also why would you go to the 60's. Why not there more injector then you will ever need thus you will never have to upgrade. i have gone from stock injectors to 40's to 55's. i wish the high z 60's where around back when i started it would have saved me alot of money. Also with the chip burners we have today they can make the 60's work on anything so to me the 60's are a no brainer
