Who Tracks Their S550 GT500 And Who Is Your Tuner?

I do and mine is tuned by Coastal Chassis Dyno out of Tampa. He does remote tunes, you data log and send it to him and if your tune needs updated, he will and then send you a new tune. He just needs to know any performance mods you have done.

I do. Have done NJMP and Pocono so far. Hitting Watkins Glenn in July, hopefully.

Ford is my tuner. Trans tuning is perfect, as far as I can tell.
Haven't needed more power. In fact sometimes hard to put down what it already has.

Only things I've done to it is some IRS cradle supports, brake air flow deflectors,
(made my own, because I can), wrapped exhaust near rear diff,
roll bar, and 4 point ASM harness (which I'm converting to 6 point as we speak).

Also just put on Goodyear F1 SC 3R's. Have not had them on track yet.

If youre running over stock power, would like to hear about any cooling mods. IC, lid, etc..?
Any issue with IAT's or pulling timing (or even traction control, but that seemed to be with
over a couple hundred WHP increase, IIRC).

I have ported my blower, smaller pulley 2.7, Whipple intercooler brick, bigger throttle body, 1050 injectors, fuel rails, 160-degree thermostat. I put in VMP's CAI and intercooler ice tank; I did this so I could have a bigger reservoir for the intercooler. Also have on long tubes with high flow cats and a catback exhaust from Stainless Works. I have run Watkins Glen, Pitt International, Gingerman and Nelson's Ledges with this set up and no issues with cooling, no overheating or pulling of power. Some of the days were in the upper 80's and very humid as well. Still running 93 octane as well.

Traction coming out of corners is something to get used to, but it is not bad, just cannot rug it too soon. I am putting down about 950 to the wheels but I also drag race the car which is why I modded it this way. I run it in track mode at the track

For how long? Why I mean is, how many minutes do you run at a time? Also, are you pushing the car hard?

I ask because non of those modifications are for cooling (other than IAT). I would be very surprised (but pleasantly so) to discover Ford's designed cooling was sufficient to track 5 sessions a day of a half hour apiece event with increased horsepower and PSI due to a smaller pulley.

Also, have you checked to know if the car is pulling timing, like OX1 asked?

Even stock GT500s pull timing under hot conditions with repetitive hot lapping...but they manage it super well and it's hard to notice. And they never hit a thermal runaway where you need to back off to cool it back down. Ford did an incredible job....but there's no margin for additional power without some sacrifice.

I have run for 30 minutes very hard at Watkins Glen where you are hard in the throttle a lot. Ford's cooling for these GT500's is great. I will run out gas before I overheat. One 30-minute session at the Glen and I am below 1/4 tank of gas from full unless I get bogged in traffic then it is usually at 1/4. I run at least four 30-minute session each track day.

I have run it at other tracks as well in the hot of summer with temps in the 90's and very humid with no issues. I have data logged and it does pull a little timing but at that horsepower you really do not notice it.

I track mine and it's all OEM drivetrain - really don't need more power in my experience. Set of coil overs will do more for you than more power.

Middleton motorsports has tuning focused on track performance and maintaining performance through a typical session. They have packages or standalone tuning, but I believe only dyno tune in-house.
