hey people hows it going? I don't know if any of you can answer my question but i hope so. I've got a '95 Gt with long tube headers, off road h pipe flowmasters, 4.10 rear gear, king cobra clutch, underdrive pulley's, cold air intake, 75mm throttle body and 70 mm mass air. And the car has no power. It has a little but not as much as i think it should. I've talked with a few people that works on mustangs where i live and they say its the computer. One told me to put an '89 mustang computer in it. and i've been told me that you can change the settings on a stock 94, 95 car computer. So i'm really confused. If anyone has had this problem and found the solution i would really appriciate the information.

It is the computer.  The '94-'95 brains don't like any mods at all.  Pro Flow Technologies has a kit for this problem and it swaps the '87-'93 computers into it.  It'll have better driveability afterwards.  Everything you have gives the computer fits so it goes into the "limp home" mode, which cuts all the power out.  You could have a chip burned, but you'd be better off with the swap.  

hey thanks for the reply i was wondering if u could tell me where i could get the informations for the Pro flow technologies kit, if it was in any of the mustang magazines or on a website. Thanks for the time man.  

MM&FF covered this a while back.  I can look to see which issue it is or you can check with Pro Flow.  It should be somewhere on their website or you can call them.  

Yeah, Eagle is right.  My '95 actually slowed down when I installed a 3.55 gear (from a 3.08).  All the other mods like off-road X-pipe, UD pullies, etc,etc, all improved the performance, but as soon as the gear was installed I could tell a very noticable difference in power loss.  My times went from an uncorrected best of 14.40@98.8 mph to a best of 14.69@95 mph at the same track, same weather conditions. However, the computer that I swapped to which was made by 'Pro-M' (no longer in bussiness) didn't help.  It was supposed to be a '89-'93 upgrade, but it didn't help at all.  Maybe the computer that EagleAuto mentioned will work, though.  Good luck.
