Have any of you guys with a 94/95 5.0 tried doing some upgrades and run into driveability problems with the ecm? i'd like to do a gt-40p heads, cobra/gt-40 intake, and cam swap into this car but i've heard the ecm's wont tollerate this much upgrade very well.
who's done what and what problems have you run into?

They do tolerate those upgrades....working on a '95 w/Edelbrock lower/Cartech upper, E-303 and Vortech....drives OK.....now, that you will be able to get the max out of them with the SN95 logic.....................-.-.-...--.. a chip or alternate (PMS/Tweecer/EEC-Tuner) will do....we're using the Tweecer R/T...it's tuning time..

now would a fox respond MUCH better to those upgrades??? if so...how hard to steal a foxes comp

A fox A9x would definetely perform better however, it's not a plug-n-play deal.....ECM pinouts are completely different. An alternate EEC is a better choice and no re-wiring needed......IMHO.

u can do certain upgrades to the 94-95 without them freaking out. the only thing u have to worry about is when going to a bigger cam. i have heard of people around here getting away with using the tfs stage 1 and e303 cam and not having driveability issues.

but me on the other hand i do but my cam is a very aggressive cam for street use but when i get tuned the shop said they cam fix the driveability issues with a custom chip. i plan on using the diablo chip

Do a Search this board...there is alot of info about the A9L computer! the 94-95 computer is kinda dumb.

Actually you can almost do a plug and play with a 91-93 tbird/xr7 pcm there are 2 highlited but a few more that are not the same check it out.
