time for a tune ?

its one of those things.... it's value depends on, "eye of the beholder". What maybe worthless to you is good for me, kinda thing. You want to get a tune? Do it. If you think you'd rather save up, add a few more mods then tune. Then DO it. You're not going to get hurt either way.... its all how you spend your money & what your aim is.

You're a pi swap and you didn't have a tune yet????????!!!!!!!!!!!! Get that thing tuned like NOW!!!!!!!!!!!!!! you need a tune in the worst way possible!!! Even if you had a full bolt on car you would still benefit from a tune. It is worth it to work out the small kinks like little blips at idle and such. Plus you make your car run more efficient and probably get better gas mileage.

Not really...would you do an h/c/i swap, while upping the compression, and not get a tune? I'd sure as hell hope not!!! Also abber, might want to try to find a set of 21 or 24lb fuel injectors as your injectors are probably maxed out.

+1... I myself fall into this category (bolt-ons w/ sct tune from AM). I've noticed a difference in HP from prior (w/o it) to present (w/ it). I think a tune is worth it if you have bolt-ons. IDK how much it'd be worth getting a tuner if you just had a stock mustang though.
if you get a new midpipe this alleviates you having to buy or make MIL elims for your CEL so this saves some money. you don't have to drive to autozone everytime you need a code read. i would say a tuner should be one of the first buys in all honesty as far as mods go even if your car is still stock.

the stock tune is very conservative. i ran around on my stock tune with my pi swap for about 4 months and it was fine. Obviously not as good as it could be... Canned tunes for pi swapped cars are still conservative though. My sniper tune for some reason was at a AFR of 12:1 and timing was pulled back so to like 13-17 at WOT. as a reference, im running my fuel at 12.9 and my timing at 24-29 at WOT now with zero pinging. I had it about 2 degrees higher then that with no signs of pinging but my trap speeds were lower with that timing so i backed it off.
IMHO, get a canned tune and a wideband and tune it yourself, you get to really know your car better. Just do a bit of research around what people with dyno tunes are running for timing and fuel and use that as a baseline on your tune. Then run it at a open track day and change your timing around and see how it affects your trap speeds.
+1 on the injectors too, i upgraded to 24's with my swap. I have 21lb ones from a stock 99-04 (or is it 00-04?) if you really want to upgrade your injectors a bit.

As has been stated in my 'stead, any new-edge GT will benefit from a tune--especially if optimised for the highest octane fuel available or that you care to buy.
The OEM tune is centered around selling cars after a very brief test drive. It has reasonable low-end torque (that can be greatly improved), and is so pig-rich and conservatively timed at WOT that there's no way you could ever, possibly, damage the engine--even if you filled the tank with ½ 87 octane and ½ kerosene...
Other than that it's not bad...

The only way that I would tune my car myself with a wideband and sniper type of software would be if I were Cliff. Other than that, I'm not willing to take any risk...ESPECIALLY when I make the move here into F/I this winter/spring.
