I want to add the 2g mass air to my car for more air and I have 650 injectors to install and have a 3inch turbo back exhaust and looking for 300+hp on a stock turbo any help I use to build mustangs now looking to beat them

Install the turbo back exhaust first. You won't need any other mods for an exhaust upgrade. You will need some way to dial in the larger injectors and airflow sensor you plan to install. I would recommend DSMLink or a modded EPROM chip from SteveP out of St. Charles, IL. Other people do custom chips as well, but I have used his services in the past about four times and never had a problem.

I agree. I installed some 550's and a 2nd Gen MAS on my first gen and it works great. I just use a SAFC-II to dial down the larger injectors - very little tweeking with the 550's. I would estimate my hp to be around 325hp at 21psi. BTW picked up the SAFC used for $120.
