He's got north of 500whp. It's not like he'll have problems beating a lot of 5.0 cars in the first place. They will need something more than bolt ons to hang with that more than likely.

Agreed, and those planning on FI wouldn't give a damn about this TSB anyway.

Wishfull thinking dude. Personally I have no fear of swapping my 08 for a 5.0 in couple years. Tuners will have it figured out long before then.

Agreed.. just F'ing with some people here.. I hope it is something as simple as leaving the knock setting alone.. Trust me.. I did enough Beta testing when the 05's came out.. now it time for the new generation to blow shit up and see what works.. haha

Its as simple as leaving the whole thing alone IF you are that concerned about warranty

Nothing in life is that simple. Us forum members are not the type to leave well enough alone. We know the 5.0 can be modded while still being just as if not more reliable than stock.

No, its pretty simple, if you want your warranty 100% then dont fool with the powertrain.

That has nothing to do with wanting to mod a car, I have no problem with that at all, just dont break it and expect Ford to pay for your (or your tuner's) experimentation.

Not that simple. If it breaks because #8s are bad to begin with, your warranty can be voided due to a tune that may have not even caused the damage.

No, it is that simple, even if there was a calibration or hardware issue you stand the chance of it not getting fixed under warranty if you screw with it.

I'll say it one more time, if you dont want to lose sleep about losing your warranty then dont modify the car. I cant see why this is so hard to understand

You're still convinced there's a problem with them from Ford, when the reality is, it's only the tuned ones that are failing. If your car doesn't have a tune and hasn't had a tune then there's nothing to worry about. If something happens, Ford will cover it. As it stands, our service bays are ghost towns when it comes to the new 5.0's in stock form.

i wonder what effect the cooling system has with this. since this seems to be situated around the #8 piston, and ive always been told Fords 7&8 cylinders run the hottest because thats where the coolant flow has a "hotspot", i wonder if we can do a "cooling mod" like back in the day on the 03-04 Cobras that will ease this problem.

I'm still not convinced. If the FRPP tuned engine can blow, then something may be wrong.

That's fair. However FRPP isn't perfect, and has to go through a learning curve as well. They may not have been aware of the knock sensor sensitivity issue before either. My buddys '10 GT500 with the 750hp Ford Racing/Whipple with the FRPP tune actually runs like shit. FRPP wants him to datalog it so they can "revise" his tune. IMO, that's something they should have got right the first time. What I'm saying is, FRPP isn't infallible.

That also a fair analysis. I'm trying to wait a bit to get some more miles on, at 900 right now. Then I'll probably break down and get a tune from Bama and/or Lund.

"infallible" is actually what I meant, but I think you know what I mean.

 

[RazorbackMustang]

It's in the tunes people. Please listen to what 19COBRA93 is saying. This engine is radically different than ANYTHING that's been on the market prior (domestically speaking, not counting any imports). It's going to take time for the tuners to learn the ins and outs of the new PCM mapping. I guess I have a tough time figuring out why everyone is rushing to slap a bunch of aftermarket stuff on a car that doesn't even have 1000 miles on it yet. I like modding cars as much as the next guy but I'm not in a hurry about it. Especially with a car that performs SO well in factory stock form.

My car has a Mac axle back and UMI LCAs. That's it. I did the control arms to help the wheel hop and the mufflers for a better sound. I have an absolute BLAST with this car! 110-111 in the quarter on a hot day is pretty stout for off the assembly line.

I realize SOMEONE has to be a guinea pig for the tuners to learn stuff, but my personal opinion is let them use their own cars. Personally, I'm not a big fan of mail order tunes anyway. Every car and every location is different. Dyno tuning is the only way to go.

My only rush is because I drive an auto. The laggy shifting when I mash the gas to handle after having a tuned 05 auto. Heck, if Bama would make me a trans only tune I think I'd take it until the engines are figured out.

Fair enough, I can understand that as it's more on the drivability side instead of trying for max powah. I'm sure someone could do that, why not ask?

Because I'm still fearful my stock engine could blow #8 and even just a trans reprogramming would show up as a flashed PCM.

Any tuner would make you a trans only tune I would think, I agree that stock an auto cars 'feels' like a slug but the dragstrip tells a different story. You can also just do a mild 91 tune from a reputable tuner and run 93, should be safe. Most tuners have backed off from their original tuning to be safe after all this anyways I'm sure.

Before I did the blower I had four different 93 NA tunes from four different tuners. The main thing I noticed was changing the response of the throttle pedal and higher RPM shift points. SOTP power-wise I didnt notice much. Trans shifting/downshifting was improved quite a bit as well. BUT, after a while if you drive it easy the trans adapts and it isnt much different than stock except for higher RPM shift points.

Good plan on waiting a little bit, as much as the aftermarket tunes 'woke up' my car from stock it would not be enough to blow my warranty over. I would make sure there is no strange noises or maybe even do a quick compression test or dyno pull to make sure the engine is healthy before loading a tune.
