I have a 96 F150 that I have worked with several tuners to get lined out, but it just isn't "right". I bought the truck for my son 4 years ago when he turned 16 with the understanding that if he didnt wreck it before graduation we'd turn it up. When we bought it , it was a "show truck" with lots of bling (most of it shiny and half assed) so I spent a lot of time sorting out charging and cooling issues due to an overtaxed charging system and mismatched cooling fans etc...It has an Edelbrock performer EFI intake and throttle body, shorty headers, cobbled together cold air kit for the factory MAF that I have fixed the vacuum leaks and corrected the IAT sensor placement and wiring. it also has WAY too much cam, sounds great but its a dog and he drove it that way for 2 years. It was reliable but truly down on power ,that didnt bother me for a 16 y/o, but after a while the nasty idling truck that couldnt pull the skin off pudding needed to be fixed. The 96 model has a hybrid OBD I/II one year only EEC system and I have worked with 3 major tuners but no one can seem to get a workable tune for it. I have spent more time and money than I care to admit and could have just bought the Holley system to begin with (which I thought about) but thought at the time I could save a few bucks and didnt need 10 10ths performance. Mechanically compression and leak down are solid, no vacuum leaks, fuel pressure is good. I haven't pulled the engine down past valve covers and intake but the internals at that level are clean no indications of poor maintenance etc.. in short I dont see a mechanical issue. The plugs look good (light tan / light grey) SO has anyone used the Terminator X Max system on one of these trucks? I know that there is a Fox system and feedback from those users is welcome but I'm looking for info on the "universal" system in particular. My son is coming home on leave soon and I'd like to at least let him know I have a plan to get the truck running right. Any feedback is welcome. Obviously this will be a bracket racer only as it is fully emissions deleted (bought that way) but I'm planning on keeping PS PB and A/C so its easier and more comfortable in the staging lanes...so off road only solutions are welcome as long as all systems work normally. Any feedback is welcome, Thanks
