My truck is a stock 1993 F150 XLT 5.0 auto SWB, the only mod is a Flowmaster Catback dual exhaust.
Has anyone used a Jet module on a similar truck?
Is it worth $239?
Is another brand of module better?

 

In my opinion its not worth the money. I had one and wasnt too impressed with it, plus my computer went bad about a year later, which may or may not have been caused by the chip. If all you have so far is a cat back there is a lot you can do for the same price of the chip with better results. Start with a cold air intake and some underdrive pullies.
