Vehicle: 1995 GT, supercharged, AODE tranny, 3.73 gears

I'm definately going to have to reprogram my shift points so that I stop hitting the rev limiter at WOT. But I'm not sure which method I have to go with to do this (I have heard two different stories.)

I have heard some people say that even though it's a 5.0, the computer on the 1995 Mustang GT does have the capability to be reprogrammed. They tell me that I could use a programmer to adjust the shift points on my tranny (to lower them.)

Others say that it's not possible with any 5.0 and I need to get a custom burned chip that will adjust the shift points.

Does anyone know for sure which way I have to go with this? Either way, does anyone have any recommendations on where to get this done? I don't really want to spend a ton of money to simply reprogram shift points...but it needs to be done ASAP.

bump for the morning guys

man i wish the usual tweecer guy's were here.....i think they can...morning to you too.


glad to see you got that done...getting it dynoed soon?

samseed101

Already had her on the dyno when I was messing around with fuel while trying to get the most out of it. Nothing great, but it's as far as I dare push the stock block anyway

grabbem88

well since i missed it....what were the numbers?

samseed101

With the water / meth running, I was looking at 318 HP / 347 TQ to the rear wheels. I have no idea what that would translate to at the flywheel (factoring in the fact that it's an auto as well.) I have heard that the HP is anywhere from 15% - 25% higher. And I don't feel like pulling the engine out to stick in on an engine dyno just to find out

grabbem88

your probably 375hp and damn good tq.

I expected a little more RWHP, but then again it is an automatic, LoL. It pulls like a MF'er though And I love the sound of it (the Procharger.) I don't think I want to add too much more HP though until I get a new engine. Maybe a 351W or something. Afraid of splitting the stock 302.

how much boost?

my freind with a rebuilt 302 h/c/i with 10 psi his making 480rwhp<he had 17psi on it and split his old one in half

samseed101

I'm running 10 PSI as well, bu nowhere near as high as his HP! To be honest, I could probably get more out of it. I'm only running my timing at 18* BTDC. With the water / meth injection I could run the timing mich higher, but I don't want to be too aggressive incase something goes wrong with the injection system.
