Im plannin on putting Dynatech Longtube headers and a catted dynatech x pipe with my magnaflow cat back I already have on the car. I already have a Steeda high velocity CAI with an SCT tune. I also plan on putting underdrive pulleys and changing the throttle body. I also want to buy an elbow for the intake. Last, I am putting FRPP 4.10 gears in the back. How much will this get me? (estimate/range?)

You know it. It is all about the tune and the beauty of a custom tune, and if you have an automatic, it can works wonders for you tranny. My shifts so much faster now without being harsh.

This is a "canned" tune. It basically means that it can be installed on any mustang. There is nothing special about it, if you have other mods it does not take them into account. Gains are minimal.

A custom tune is one where a tuner (B amachips, Brenspeed, Evo etc) ask you for other mods you have and them actually write a tune for YOUR specific car. Yes you can load it into another car, but it is meant for your car only. This is similar to what a dyno tuner can do. Gains are very good. For just a CAI and tune you can get 25-28 HP.

A dyno tune is best because they actually have your car and write a tune for it and it can be loaded into a tuner so you can still return to stock when visiting the dealer. Gains are the best here. They can adjust your air/fuel ratio to exactly where it should be.

Alright, here's another question for you guys.

How woulda 300RWHP Automatic GT with 3.73 gears (and a tune) perform in the1/4 mile and 0-60?

look at my sig.....with my mods I am getting 300.8 RWHP 304lbs torque......thats with CAI, TUNE, Kooks LT with cattted x pipe and thats it....I will be glad to post the dyno sheet..

umm actually all i have is a C&L intake and a sct tuner. the only difference is i got a custom dyno tune from Amazon Tuning Solutions. And i went from stock to 311rwhp/ 319rwtq. so i think what you are striving for is a really good tune.

btw i got some sheets to prove it.

howarmat

you state in your sig you also have a x pipe and no cats....so that can add some HP too, 8-10+ i have heard......I am not saying with a dyno tune you cant get to 300 with just a CAI and tune. But no way with a canned or even custom mail tune really unless it just happened to be absolutely perfect.

It is a "canned" tune, but not from any special place like B ama, or Brenspeed, or anywhere else. It is the tune that came from C&L on the predator that came with C&L CAI in their tuner + CAI package...and my A/F ratio is dead-bolts on!!! The guy at the dyno shop figured that at most he could probably get another 5-10hp...So we decided to wait until after my headers....

Take this with a grain of salt, but when I had my tune put in a my car dynoed on a Mustang Dyno they ran two 1/4 mile simulations of 12.72 @ 107 mph and another at 12.78 @ 107 mph. Now that sounds a little quickto me even with the 3:73 rear and custom tune. I was expected more like a 13.20 to 13.30 range since it is a convertible which is 150 lbs or so heavier than a coupe. Anybody else out have about the same set-up and have actually ran theirs on the track where it really matters.

A dyno can't simulate traction issues, along with a world of other things.
