Hi, im a newbie here. Got a question for ya'll. I bought my 07 gt used with 27,000 on it. It ran great! Unfortunately i live in a county where you have to pass emissions. Previous owner did not.

When I got it it had a C&L cai, an offroad mid with flowmaster exhaust, and obviously some kind of computer tune but no programmer with the car. Dealer had to put everything back to stock except the flowmasters. They gave me the C&L so i have that to put back on.

Here's the problem and where ill start the arguing: ive read u have to have a tuner for the cai to work correctly, the big question is which should i get? the sct or the diablo??

ive read a few opinions for both but would like to get some input. also with stock headers does the cat mid pipe REALLY make that big of difference because the tubes seem same size as aftermarket. Its jst such a hassle to have to go back and redo everything every year to pass. Plus very costly to have it done by someone else.

Both SCT and Diablo are good, but more custom tuners use SCT than Diablo.

The reason for going with an SCT is more tuners write for it. Also email tunes are easier to download due to the usb port. Diablo uses a serial port for downloads.

Most email tuners will give you 3 tunes for your car with the purchase of the tuner.

i spoke with a guy at the only local performance shop and he said they sell both the diablo and sct and he seemed to lean toward the diablo saying main reason he does the sct is just in case a customer comes in with one he can still dyno and everything for it but was kind of pushing the diablo. is sct really much better?

Are they just selling the tuners with the canned tunes or are they dyno tuning?

i know that i am about to get the sct livewire for my car because of the user friendlyness and the fact that most tuners have tunes for sct. also the sct's usually come with a few preset tunes, one of which is usually an "economy tune" which could help with the emissions issue, however a good dyno tune with most mods will still pass emmisions, i dint know how strict things are in your area but ive seen a few guys run highly moded cars, and pass emissions with agood tune.

some tuners will only hold one custom tune, i know some of the sct's hold up to 3 custom tunes.

so if you choose to use a custom tune does it still retain your factory tune as well so that i can just flash it back to pass marta and then reinstall custom? adn can u have one for performance and one for economy and how hard is it to switch between them? its not like a one button push when feeling froggy is it?:gringreen

Yes

You can have as many tunes as your pc can store, but the tuner will only hold 4 and not it's not that easy. You have to turn the car off...it takes about 5 minutes to switch tunes.

+1 on the Tillman speed, If it were me I'd buy it from Tillman talk to Chris Rose, and he'll send you one with custom tunes, I've had great experiences with Tillman!!!

well, i just called and talked to a tech support with diablo and he said that the predator will hold up to 5 custom tunes along with the canned tunes that come on it. He said i would be able to switch between the custom tunes and canned tunes with no problem. and after i put on the cai if i swap out to an offroad pipe will i need to have another tune done? I really appreciate all the help ya'll are providing!

Get the SCT. Get your tunes from Tillman.
You will likely only use one or two tunes other than stock. There is almost no point in having 5 available tunes.
