How important is a tune after bolt-ons?

Okay, let's say you've done the CAI, TB, Plenum, UDP's, and exhaust. How much difference will a good tune make? Comments and recommendations appreciated...

Re: How important is a tune after bolt-ons?

Are you referring to a dynotune or a mail-order tune? You'll see 10-15 rwhp from a good tune depending on the place. There's always more benefits from a dyno tune just because it is hands on one-on-one tuning. What you need to ask yourself, however, is what else are you wanting to do to the car. If you have more plans for this car in the next year or so then I'd wait to have a tune done just to save some money.

Yeah, tune will "always" get you more power, even by itself, but it's not really neccesary on your car yet. But it would make a difference.

Re: How important is a tune after bolt-ons?

I have the same mods as you except for the pulley's,and the car sure runs like **** below 2000 RPM's and when the engines cold I have to let the car idle for about 20 or so seconds after I start it or it will stall when I start to take off. And yes mail order tunes are ****, I order a SCT xcalibrator through the mail and it only made it run worse so I set it back to the stock tune. If your car is have the same problems as my then I think its worth going ahead and getting it tuned, I think I might call tomorrow and see about getting mine done.

Are you sure you got it from a good place because I used a SCT Xcalibrator 2 on my car and the only problem it gave me was I now have to be very careful when I accelerate Or I samoke the tires

Re: How important is a tune after bolt-ons?

No doubt a dyno tune would be better than a handheld. I like the ability to "return to stock tune" as my engine is under warranty from Ford for almost 3 more years.

It just doesn't run very smooth below 2k rpm. No stalling or anything, just not very smooth. I'm just trying to figure out if I need a tune or if there could be other issues. The motor only has 2.5k miles on it and I know I broke her in proper. But I reused all intake, injectors, and accessories. Maybe bad gas;low octane, dirty injectors????

Suggestions appreciated!

:dunno: Sutton High Performance - Car Parts, SCT, Ford, Modular Engines, Mustang I ordered it from here. I told them what mods I have, and it just amplified the problems slightly. Don't get me wrong I think SCT makes the best handheld tuner, Im just not going to start making changes with it myself.

A tune is not required, but you could benefit from a good mail order or dynotune. I would stick with SCT products.
