Powerdyne says stock MAF and Injectors are okay w/9psi kit

[Foxed]

A friend of mine(Aaron) just ordered a powerdyne 9psi kit that comes with Fmu, chip and fuel pump. I told him he should get lager injectors and MAF but I guess he called powerdyne and they told him the stock maf and injectors will be fine. Oh they also told him that the kit will add 125hp The car has 125k miles, headers, H, flows, and 373's.......I would like to know your thoughts on this

No idea what to expect from the Powerdyne but the kits these folks put together will usually support the blower that they accompany. I've been suprised on more than one occation with how much actual rear wheel HP a set of 19s or 24s will support with an FMU and decent tune. I currently have 24s installed in combination with a Blowzilla and a few other mods. I'm at the limit of what I can do with those injectors but also suprised I've gotten as much out of them as I have.
