if it hasnt been realesed yet, how can you recommend it?did they do the testing on your truck?

 

I had one for my 01 F150 and it made a world of difference. They have put alot of real world testing into this unit as well. They make a superior product.

 

i was just wondering.i am buying the jet stage 2 chip off of another forum user to try out. i want to see how it compares performance wise to the 3815. i also had the hypertech max energy.the hyper got me 2-3mpg's more.the sc had more hp.not alot maybe 5 or 10.but you could tell.gonna try the sct after a few more mods.(1.7rr, underdrives,exhaust)
