I just bought a new '08 V-8 GT Mustang and I'd like some advice on economical, safe modifications to increase the H.P. I'm new to Mustangs. Up to now I've built Chevy Small blocks. Love my Mustang!

Tuners
Cold air intakes
etc.

Thanx in advance for any advice.

My advice is that you not change a thing for at least 20K miles. Not only will that get your engine broken in, but it will also give you an idea of how to drive that monster to decide if you really need to add any more horses.

When you do decide to mod, I've done an SCT Tuner, Flowmaster Cat-Backs and C&L Cold Air Kit and I love it. Nice safe horsepower gains.

Just wanted to say, I put my mods on at about 3000 Miles right after the first oil change and I haven't regretted it.

additional mods should include underpulleys, Ford shorty headers, hi flo cats with h pipes and 3.73 gear
