Is the bama tuner really worth the $400. I have cai, x pipe exhaust.

CiniZter

tuner is worth it even if you end up dislike BAMA you can get anotehr tune installed through the tuner.

buy a used one and save some money as long as it's not married

What kind of gains should I get with a tuner, cai, x pipe exhaust, magnaflow axle back exhaust. 5 speed manual ? Just a rough guess.

07 Boss

5-10 hp

So all the mods on your mustang must have netted you about 25hp? I don't think 5 to 10hp is very acurate assumption. tuner itself should be 10 hp.

I have a Bama tuner for my 07 GT (JLT cai & axle backs), the car is a whole different animal. Throttle response is amazing. Worth every penny!

07 Boss

??? A tuner and CAI will net you 10-15 at the motor, maybe 8-12 at the wheels. I said 5-10 so as not to get the your expectations inflated. The exhaust won't net you much unless you delete the cats and I didn't see any mention of an O/R pipe. And if you were to delete the cats that's what, another 3-5? Probably closer to 2-3.

And if you're so good at bench racing, How much hp should my car have with the modifications I have done? Let's see how close you are at guessing at HP numbers. I'll even help you. The pulley is an 11-12 psi pulley. I make about 10.3 psi of boost which means I make a little more power than your standard motor at 11-12 psi. And I only run a max of 16* of ignition timing instead of the standard 18*-20* that most people run with this kind of boost and pump gas. You should be able to nail it on the head with all of that info.

Why everybody thinks there cars are soooo much faster with a tune is because of the ramped up throttle position. It's the same thing as stepping on your gas pedal farther. It just seems like you have a bunch more power.

What about the dyno sheet we see with 30 hp gains at the wheels? That is with a intake and tune.

07 Boss

Yeah OK. I can show you dyno sheets that say spark plugs will net you 25-30 hp too. I think there's even a video. I Suppose you're gonna want to run out and buy those plugs.

By no means am I saying don't do it. It's probably the first step in building a good car. I'm just saying that you shouldn't set your expectations up for disappointment. Don't listen to all those up numbers that people throw around. Have reasonable expectations and you won't be disappointed. They are just arbitrary numbers. And they get exaggerated and manipulated. I don't ever talk about hp numbers when talking about cars because they don't mean ****. If you wanna talk cars tell me how fast it is, not how much hp it has. HP is a made up number anyways.

So there's a lot of liars out there. Steeda? Brenspeed? many others? OK

05YellowGT

Here's my dyno sheet from back in 05, the red is with Steeda's axial back exhaust, pulley's and tune, the blue is after they added the CMD plates. I don't have one from when it was stock, but the ones I saw had between 250 - 270 RWHP for our cars.

07 Boss

I'm not saying liars, but they embellish numbers quite a bit. Everybody does, it's marketing targeted toward the bench racers. I'm not going to argue about it, I'm was just trying to be realistic, not idealistic, with the OP and what to expect. I've done my share of car building and tuning over the last 3 decades and have learned to take advertised number with a grain of salt. Usually those numbers are in house under ideal circumstances, not even close to what happens in the real world. If you look at the mods my car has it should make over 600 hp at the motor. You and I both no that my motor would not be spinning anymore if that were true.

I will concede that a good tune on a stock motor may net you 5-15 rwhp (went up 5 hp from previously) But gains from a CAI will only be there if your current set up is a currently a restriction. And the amount of the gain will only be as much as the current restriction in air flow is relieved. And bigger is not always better. Air flow velocity through the intake and heads will play a bigger role sometimes than sheer volume. Same goes for exhaust. Putting a 3 1/2" exhaust may hurt your performance by slowing the velocity.

There are too many real world factors that need to be taken into consideration when modding your car that are going to make it different than what the manufacturer claims are.

All I'm saying is don't be disappointed when instead of the 25-30 hp that is advertised only nets you 8-12. I've seen it too many times.

Another thing to remember that peak numbers don't mean squat either. it is all about the area under the curve. Here is a perfect example, delete plates added 5 peak hp but look at the entire graph. .4 ftlbs of torque. Remember, hp is a made up number, torque is the measure of how much power is being made. No gains until after 5K RPMs. Made some good torque gains after 5500 which when converted to hp is exaggerated because of where it is in the RPM range. But the entire graph below that point is even, if not less, than where it was prior to the install. And that peak 5 hp gain looks like its well above 6K RPMs. Depending on how you drive these gains are pretty much zero. If you are drag racing you will notice a difference.

Another interesting point on this dyno chart, does the increase in power have anything to with leaning out the mixture by almost a full point?
