It depends - on the tuner....
the sct proved useful for 144,000 miles on my 05 6.0, but so far haven't looked at anything for the 6.7... (but will probably, more than likely, it's a sure bet !
)
5star tuning is a sponsor of this site. Their product is SCT. They do a great job wakening up our V10s. Give them a call or email Mike directly. You won't be dissappointed.

1. There are plenty of persons who advertise their programs to be the best and even offer custom tunes, but in all reality, very few actually have credentials in these areas- but that’s not to say that some of these “geniuses” haven’t really caused damage to a few vehicles- just jump over to flatratetech.com and read just some of the comments from the MSE techs!
2. Perhaps what is equally important is the parameters that can be adjusted are set by the OEM vehicle software…so there is really no “magic” in what they are doing anyway.
3. If you look at the dyno charts from many of these supposed HP/TQ increases, they are typically around 5%-7% at peak rpm ranges…….guess what, 5% is a standard deviation even amoungst mfg dynos
4. For any tuner to claim they can by remote means, never see your vehicle, never look at the data logging, etc, to state they can "create this great tune, ie increase HP, TQ, etc" is simply false advertising....no different than the "tune-Up Masters" that existed in the 70's & 80's...yeah, for $29.95 we will tune any car! Yes, they installed the cheapest plugs, etc they had and only replaced the parts they absolutelyhad to...basically, most people recieved a $5 value tune-up...that lasted for just over 6 months...you bet, TUM's warranty!
5. These "tuners" are unregulated and unlicensed- menaing if a mechanic physically re-tunes your vehicle, they are regulated by the state level department of consumer affairs- how, what, when , where and why they do it...and if they screw it up, well, they eat it.......try that with any of the "Custom mail Order Tuners"...unregulated and answer to NO ONE!!!!!!!!!
6. The issue "we have never damaged anybodys tranny or engine" is false....There are pages & pages of postings that ask for help, but this one clearly represents the work of one of the most well know tuners in america....................check out...Roush Dyno Tune

Bad situation-Need help! - Vintage Mustang Forums
To make an extremely long story short. I need someone to tell me who to talk to for help. I have posted several times and got a lot of help. Got my engine build finished in May. Ran great. Took it to Roush Racing for a tune. It is a 93, efi, 302 with several upgrades. Went to get it from Roush and the water hose had blown and torn up my brand new hood I just had painted. It can be fixed. Drove the car home and it would not start the next day. Finally found the adapter between the TPS and painless harness was missing. Fixed that. It would not idle consistently. Took it back to Roush. They said it was fixed. Went less than 1/2 mile and it was idling at 2500 rpm. Took it back. They were lost. Said to bring it back. Never did since I had no confidence in them. The head of the dyno room called someone else for advice. Took it to a friend who restores cars. He went back through all the wiring (Painless), changed IAC, changed to stock computer, and ran diagnostics. Never could get to idle consitently. Still between 1800 and 2500. Read the forums and found Pro Dyno in Rock Hill, SC to be one of the best. It has been there for 6 weeks now. Changed computers again, IAC, and TPS. Added FPA headers and Magnaflow 2 1/2 exhaust and retuned. Pulled over 300 rwhp, 330 torque and they told me to come and get it. I drove it around the block and it ran great. Was going to get gas across the street and it went crazy again. Then it would not start until I bled the fuel rail. It is still there and they are lost. Only suggestion is to start changing parts which are all new. It is now grounded to the frame=twice, battery, and body twice so it is not the ground. It could be coincidence but I have not been able to drive it anywhere since I took it to Roush in May. Pro Dyno is supposed to be the best and they are baffled. Only way they could get it to idle correctly was to disconnect IAC. I need help. I am totally disgusted. If you need to talk, PM me and I will give you all my personal contact info. Thanks for any help. I am out of options.
IMHO, if you live near any major city there are excellent tuning specialists with dynos who for the same price (if not less) will tune your vehicle taking into consideration your specific needs including environmental conditions, for your specific vehicle. IMHO, the best bang for the buck!
If you are comfortable and understand how to tune a vehicle, you can also do this yourself. There are several software programs available, that “Speak Common English” that will allow you to tune your vehicles ECM. One company is HP Tuners, they have a website….they offer two core programs, one for those who are doing dyno tuning and one for the home-garage mechanic (which is priced at about the same as most of the “canned tunes on the market) …this version limits the span of adjustments as a safeguard against doing something outside of the oem scope……basically, keeps you from doing something “too stupid by accident” (grin).
