My tuner says you can't get much more

There is a shop about 20 miles from me that we all take our Mustangs to for dyno tuning. He's a former Ford mechanic who went out on his own to focus on performance for Ford vehicles. He tuned my bolt-on 2001 GT and got 40 HP and 50 lbs/ft of torque out of it. I was shocked. He does really good work and people come from other states to have him do their cars.

My father was talking to him yesterday about doing some work on his GT500 and while they were chatting he mentioned to the tuner that I have picked up a Mach 1 that I'd like to get tuned soon. The tuner told him that on the Mach 1, there isn't much gain to be had. He claims that on these specific cars, the tune that Ford used is really good and is pretty much at the limits already. He said there might be 3-5 HP to squeeze out, but without doing headers and more serious mods, there isn't much that you can add to the tune itself.

Have you guys been told this by your tuners? I want to keep this car closer to stock, so if 3-5 HP is all that's left on the table, I'm not going to spend the $450.

Re: My tuner says you can't get much more

Your tuner is right, there's not a lot to be gained with tuning until headers, ported intake etc

Re: My tuner says you can't get much more

Hmm ok. Sounds like I probably should leave the stock tune in the car then. I don't plan on tearing into the engine on this one until it dies. Thanks.

Re: My tuner says you can't get much more

About the best I got from mine was reaching the advertised HP.

ported intakes add little; low bang for the buck.

A good dyno tune is worth the investment, even if stock.

Haven't ported intakes been reported to pick up 10-15hp on most mild (N/A) combos?

Whats a good dyno tune worth on a bone stock Mach 1? I know when mine was ported intake and longtubes it put down 310 on the stock file. After tuning it was 318. It didnt seem from my experience that Ford put a lazy calibration in these cars.

Money-wise, a flasher/chip plus tuning is about equal to the cost of a ported intake. An intake may even be cheaper if you find a "deal".

In summary, neither is a very good bang for the buck when you live in a world where options for boost are everywhere you look. But I understand and respect the desire for N/A power. Nobody loves stock cars on this board more than I do.
