few question about the 05/06 gt

When I called the people at SCT they told me I would actually have less power if I didn't tune it and put the intake on than if i stayed stock. Now obviously they want to sell their product but I have seen much the same info backed up here on the forum. Basically I think any power mod you do to these they need to be retuned....gotta love those computers.

I wouldnt resort to posting that the ECU sucks, "strict" would be a better term to use.

My theory is that Ford wishes to keep variables out of play in their units for fear of too many warranty issues. Its been stated that even if Ford tech find that you have modified the tune of the ECU that you void any and all vehicle warranties.

I am not bothered much by this new generation of ECU, there was a day that I was a "carburetor cowboy" back in the classic forums. I was scared to think what hell it must be to produce full throttle power as well as part throttle power with electronics (known to have inherit issues) over a mechanical set of barrels. I have come to sense that it really isnt much trouble at all with a support network already in place for safe enough tunes for the masses.

Of course I wont spray my Stage 1 without dyno tuning time with that very important wideband air/fuel sensor.

The new 05 Computer (Spanish Oak) is a seriously controlling item. If you do some research you will see that the only thing that you can do to the 05 without touching the computer is adding some stickers.

Now K&N advertises that one doesn't need a tune but I wouldn't trust it. I have seen some dyno graphs that show WAY Lean cars with such mods. Most good parts companies sell a reflasher with their cold air kits.

And as far as a GTP going to 480hp without touching the computer… I wouldn’t try that. There is no way the stock programming provides enough gas to that thing to not detonate.


PS I was going to buy a 07 Cobra, but I EXTREMELY glad that I bought this GT
