Diablo for 4.2
Ken, I was hoping you could tell me what I might expect out of a Diablo chip on my 2002 4.2L 5speed 4x4(box code EFK1). I would also like to know if it would cost any extra to have the modification done so my computer would know that I am now running 265/70/R17's instead of the stock 255/70/R16's. And also, if the Diablo is even what I should be looking at or if there is something else better suited for my truck. Any help would sure be appreciated.

Diablo for 4.2
Sorry for missing this....
Anyway, here's what I get from both specs sheets and my own experience programming them....
Of all the engines used in late model F150s, the 4.2 is the finickiest. Diablo rates the chip at 19 horsepower and 28 ft-lb torque. Superchips rates it at 21 horsepower and 15 ft-lb torque. The Superchips, in this case, has an edge at upper end HP, the Diablo has the torque (ie, lower end) edge.
When the chips work for the your 4.2 ECU code, they work very well. However, I've had higher than normal incidents of the 4.2 not responding or not responding well to a chip. This doesn't mean that it won't work for you, it just means the odds are a little higher that you won't see a gain (or much) with some codes. That's precisely why both companies have a 30 day money back guarantee.
