86 f150 chip/module help
i have found a chip and a module for my computer and am having trouble deciding which to go with and would like you help.
Computer Chips/Modules - summitracing.com
theres the link for the 2 items. Im also wondering if anyone has any experience with these or if there is another chip or module i can look at. thanks

I wouldn't hold out much hope on that. There honestly isn't much in a 1986 F150 computer that is tunable. You'd be better off adding two degrees of timing on the distributor and leave it at that.
Take care.

There is a LOT to tune in an '86 computer. You have fuel curve vs ignition timing. You can change the signal back to the TFI module to allow for more base timing. The problem is that you really need a laptop and tweecer to get it right. Then it's a process of trial and error.

Since much of the gains on those years come from timing, you basically confirmed what I said... Advance the distributor. You don't need a program to do that... just a 1/2" wrench. 
Now yes, ideally a setup like TwEECer would be cool since it offers the ability to adjust the fuel curves as well as the timing. Just keep in mind that the early computers are very minimal function and don't have anywhere near the processing capability or function that the later EECs do. Of course, they don't have all the emissions foolishness in them either so they are a bit easier to tune in that respect.
If one was SERIOUS about getting into their ECM and poking around, that's fine. But I just wanted to point out that there are some less expensive ways to pick up a little performance.
