Ok recently I e-mailed Jez. Who owns Horsham Developments, and has also built and tuned many CA's. Well I was looking through his website.
http://www.h-dev.co.ukand mainly at the stage 2 chip. It is supposed to support 270bhp, or roughly 250whp. This is on the stock injectors, and stock mafs.
I thought to myself that I saw somewhere on here that the ca MAFS was good to only 190whp. So I decided to send Jez an e-mail and ask him how the stage two chip uses the stock mafs.
His reply was that the stock mafs is good to around 270hp and that it would be easy to achieve 250hp on my set-up using stock injectors and stock mafs, as long as I have the walbro pump and stock FPR.
So my question is, what is the mafs good for?
