Default HP Gains with Tuner

Hello Again, Im sorry if i keep asking stupid questions but just trying to learn whats a waste of $$ and what mods arent. Anyhow, I was told that a custom tune with a CAI would give me about a 30-35hp gain on my stock 03 GT. Is this true? Now from reading on here, it seems that i can save $$ on the CAI.

Now what would be best for a stock GT, an SCT tuner or a custom tune?
Im assuming, since i dont have any mods yet, I should just get the SCT Tuner and then send it back for a free BAMA custom tune after I have added some mods? I would guess a custom tune is a waste if i dont have any mods? Im planning on the CAI/K&N drop in filter, x pipe with catback magnaflow, 3.50gears (if thats possible) and a transgo shift kit.

Whats your advise and opinions.

The canned tune on the tuner will give you pretty much as much as you're going to get from a tune. Save the custom tune for when you have some substantial stuff done.

If the x-pipe is going to be catless, you'll need to adjust for that in your tune. 3.55 gears do exist, and again, a tune adjustment will be required. You may be able to forego the shift kit with shift firmness adjustments in the tune. It will be nearly as good with modest power.

Advice: Wait on the custom tune, get the exhaust and gears done at the same time, then plop for the custom tune.

Yeah, the canned tune will be your best bet for right now. You won't gain 30 hp from the tune and CAI though. More like 15 hp in reality.

Forget the CAI, your car came from the factory with a CAI and a pretty good one at that.

As to "30 to 35hp" gain from a tune, whoever told you that was full of bovine excrement. With a tune optimised for 93 octane you will find 7-10HP peak (+5%), and a 10-15HP in the mid-range--where it will be a 7% to 10% increase--and also where it's worth a lot more than anything added just before you shift.

3.55 gears are available, however as they are not much of a change from the stock 3.27s I would recommend 3.73 or 4.10 depending on your driving habits and overall plan...

There is very little you can bolt-on that will add any significant power without a custom tune; opening up the exhaust is about it.

The stock tuning has very conservative ignition timing and runs pig-rich at WOT (as much as 11.0:1) so that it will never ping on 87 octane fuel under any conditions. A dead stock new-edge GT will benefit from even an 87 octane optimised tune.

I have tuned a number of stock GTs and never had anyone come back from the first drive without a grin on there face...

Tuner SCT X3 headers and x pipe all depends how much you wanna spend and what kind of sound you want. People say the Prochamber pipe is the best. as for headers I would go with in my opinion BBK.

Hey Cliffy..Come back

Can you explain alittle more in detail about this ^. You got me really curious. I know by reading alot of your post you know these cars pretty well.
Is the stock tune that bad over a SCT CAN 87 tune?Lets say.

Thank You Cliffy ahead of time
