My name is Zac, I'm new to the Mustang world. My previous project was a 1990 Nissan 300ZX Twin turbo that i built up through high school and turned into a total beast. I just recently bought a 2007 Mustang GT Premium with the 4.6L V8. Ive already added a catback exhaust and am looking to add a cold air intake soon. My question though involves Flash Tuners. Ive heard a lot of good things about them, but was wondering if you all could clarify some things.
1) Will it void a factory warranty?
2) Could i change it back to factory specs?
3) Would it require strengthening my internals?
4) What kind of hp and torque gains could i expect?
Keep in mind that i also have a budget of about $1k right now. If you have any products you recommend I could do with that as well.

Thanks,
-Zac

Welcome the Mustang World! check out brenspeed or bama chips site they both have a CAI and tune combo.
Yes you can load back to factory settings. As long as you load up the stock settings before taking car in to dealer for service, that's what I do. You can gain about 20-25 hp with the CAI tune combo and you can feel the gains with those two mods. I think It's the best first mod next to gears and tune IMO. I Think for around $600 you can get the CAI and tune combo. so that still leaves you with some extra money to play with.

Oh and I use to have a Z31 turbo With full bolt ons. It was a fun car till the motor blew! I always wanted a Z32 TT but never got one. Is your GT auto or manual?

Dude, if you buy a car like a GT its gotta be standard. So yeah, manual. lol

Welcome to the forum. All your questions can be answered by the search feature but here's the rundown:

1. No, it won't void your warranty but some dealers will try to intimidate most wusses.
2. The CAI & tune combo (highly recommended to do both as a package) can easily be removed and the tune returned to stock.
3. No, not unless you go FI. The 4.6L stock is good for about 450 HP.
4. Expect anywhere from about 15-25 RWHP or more gain. Our stock engines AVERAGE about 255-265 RWHP off the lot. I can't say what the torque gains are, though.

The CAI & tune combo, preferrably from the better tuners such as Brenspeed, Bama or VMP, run in the $550 - $700 range and are considered the best 1st mod and IS the best bang-for-the-buck power adder short of going FI. There are a lot of nickle and dime power adders out there plus weight saving mods that'll free-up some HP. Again, the search feature is a big help. Unfortunately, your axlebacks only add sound and no power as the stock exhaust breathes very well short of losing the cats and adding headers.

Hehe just wondering cause I was going to say I heard good things about the flash tunes on auto. But yeah I know what you mean. So yeah check out those site's and see what you like I don't think it matters what CAI intake you get that's really up to you.

Zac07

Thanks for the help. I appriciate it.

FYI, adding the CAI w/o a tune will likely cause you to throw a code, even with some of the CAI's that claim to not require a tune. Our PCM's can only adjust for so much air with a stand-alone CAI that it'll often lean out. The tune is the bigger power adder of the 2; roughly 80% from the tune and 20% from the CAI.

Alright. That was gonna be my next question. Thanks man
