Factory tune my car ran lean, even after an E-tune the car was still lean in parts of the pulls.
Not until my custom tune did it run where it should be.


I havent had a problem with warranty through ford. Before you go load in your stock tune and i install my stock intake and baby it to Ford down the street, then reinstall when the work is done.

In that flowchart above, the 'P1000' code means that the computer's readiness codes are not set. In other words, it has a new computer calibration and it's still learning to communicate with its sensors. It normally takes a few hundred miles to remove this code.

This is a telltale sign that someone has done exactly what you describe. Please note where the chart goes from there.

I agree I need a tune. Instant throttle response and another 15ish horsepower would be nice but the car is so new I don't want to screw the warranty. I want to get at least 15-20k on it first.

I feel the same way, I'm going to let the warranty expire before I do any mods. I had an 02 Lightning that ate a transmission and it cost me a couple of thousand dollars. I want to hear no excuses from Ford if something goes wrong with my new GT. Once the warranty expires, KB LC blower, LT, full exhaust and then we see whats up crackers!

Egg Zachary!!

<-----shopping for mine.

I'll do a mild exhaust, mgw shifter, MTX redline transmission fluid, and oil changes with ZDDP additive for my only mods until the warranty is at least half way through it's term. All the while saving up for the 7** hp mark.

Sold! lol

Most of the 6 speed manual cars make anywhere fro 380-400. I have seen a big gap in dyno numbers on the new 5.0's. We had one come in that made 405 hp bone stock. Keep in mind guys that Saturday was cool temps and the humidity wasn't crazy high so cars should have been making good numbers.

dyno jet reads high though.

[90GT50]

dyno jet reads high though.

No, it doesn't. It reads normal. Dynojet on SAE, smoothing 5 is pretty much industry standard. The only people that say they read high are people that use mustang dynos, because they read lower usually.

[Sam88gta1]

The numbers are high because its in STD not SAE correction. SAE in this type of weather is 2-4% lower than STD.

Get back on the beat, flat foot.

Buncha lightweights worrying about the warranty. You pays your monies and you takes your chances. Either you can afford to play, or you can't!
