Will a tune ever be in your future ????

Probably not anytime soon. I think the 20-25 rwhp gain that I'll likely see doesn't outweigh the loss of my warranty. I'm satisfied with the power it makes now. So well balanced to the chassis...

The air/fuel ratio with the red key and 84.5 mm TB look a little lean, actually a lot lean, if you run that on a road race course you may just need the warranty. A tuner will get that into a 12.2 - 12.4:1 mixture and keep it from burning the pistons down during sustained running at WOT.

Agreed.
Good call Steve.

Good call Steve; I agree on your a/f observation.
I will say that When I called Accufab they were totally non-committal when I pushed on whether the factory tune would unconditionally accommodate their TB.
The guy I spoke, with who was a "Product Manager," had never heard of "Track Key." - That alone was enough for me to stay away.
As per RRBOSS302's intentions I do not think the security-blanket logic holds up; there will always be issues.
What the heck, we all know how flaky even Ford's tune/computer/harness/sensors, etc. can be, so RRBOSS302's dilemma is not unique.
Having said that, I too was hung up on the warranty paradoxes of enjoying a "factory hot rod."
However, the RR power plant now more that 2 years old is no longer an unknown.
There are plenty of good tuners who can create reliable maps for this beast.
Unfortunately that doesn't help RRBOSS302 either and none of this really addresses his warranty concerns.
...Bottom line: Ford could easily attribute any problems to "out-of-sight/out-of-mind" bolt-ons whether the part is in the Ford catalog or not.

This kinda reminds me of the BS we all went through with vendors trying to answer questions with a straight face about KOOKS LT cat issues a while back.

That throttle body has Ford Racing laser etched in it for a reason. So you get a 2 year warranty on that part for manufacturing defects. Read the FRPP catalog disclaimers, if a part doesn't have the 50 state legal icon it is an off road/racing only part that can and void your new car warranty if deemed to contribute to a failure. You can bet if an engine fails that TB will be identified as a cause along with the non OEM intake.
In event of failure you could game the system by removing the offending parts and reinstalling the OEM parts, this could be construed as fraud though so be careful. I personally have no engine or drivetrain warranty since just about everything is modded.
Food for thought.

I concur with the 'a little lean' side of things and have been wondering for months why nobody has said anything about this yet. Especially on SVTP where all dyno charts get heavily analyzed and scrutinized.

The reason I believe this car was making more power with the Red Key is because it's programmed to run a little fat on the top end and the slightly under-metered setup can take advantage of it, then apparently squeeze a bunch of extra ponies out. The tradeoff is that you are taking away the intended safety buffer and cooling which should come from running a tad rich. Even if detonation isn't an issue, I'm sure this setup would run on the hot side on track.

So... I should expect you by later today to assist with my roll bar installation... or at least to drink beer?

;D

Unless you have an AED tuned car than your dyno sheet was printed from God's computer and is golden lol.

Well mine didn't last week with temps in the 80's but next weekend will be a real test with temps in the 90's. In fact last weekend my car ran surprisingly cool and I was watching it closely. Never saw CHT above low 220's using TK.

It'll be interesting to hear your results. What track was that last week? You're probably at less risk for overheating will with most or all of your tracks under 100 ft msl, and even less so with the bay area humidity.

EDIT: typo

Low humidity for the bay area is still like 40%! It's relative relative humidity. ;)

Over here, dry is in the teens...or less :(

We probably should be cross checking humidity in the oil cooler threads too.

EDIT: Next week is Thunderhill? Good luck and watch your temps in the afternoon. Do you still call that 'Central Valley' up north?

Steve-

You should start or resurrect a build thread with your complete build!! It's a great example of what a lot of us eventually want to with our cars.
