Having second thoughts about the PPE now. I have been reading on here about Autocal. This is a handheld tuner with EFI live loaded into it correct? How much is this? I am mainly looking for a economy and tow tune. I do not need the ability to to switch on the fly, so the switch is not needed. My truck is about as stock as you can get with the exception of an AFE mouthpiece. I can get the PPE tuner for $250. How much more would the Autocal be tuned from Kory?
