so i have seen this talked about before but specifically i wanted to ask about the economy mode.can any one out there who bought this and used economy mode tell me how much of mpg improvement it made? since gas prices will only keep going up if this helps even 2 mpg its a good investment.im not interested in the other modes just the economy mode since i drive my single cab shorted mostly highway

It's not going to be enough to pay for itself.

Know nothing on the Jet chip, never read one. But I can say for 100% fact I had my old TBI tuned for both maximum power and maximum fuel economy in the same chip. For economy drive with a light foot and for power just step on it. I was up a solid 20 hp, 30 tq and 3 mpg over the stock tuning. Mildly moded 350/4L60E and 3.08 gears in my 1983 G20 that was running a stock 1995 TBI G20 van computer prior to tuning it.
