I have a 92 F-150, 5.0 with E4OD and positrac rear end (3.55). I get soft shifts between 2nd and 3rd. 1st to 2nd and 3rd to overdrive are good. Will I see dramatic results from chipping, as far as clutch slippage?. What would be the price of the chip?

 

So long as you have an electronic transmission the chip will help firm up the shifts. It WILL NOT help if the clutch packs need replacing. Don't have a Diablo for your year so you'll need to go with Superchips. Pricing can be found by pressing the Online Store link.
