Ok I think I found somthing, my cylinder vol is set to 744.15 and i have a 383. If I use the formula CI/61.5 x1000 / 8 I get 778.46. This may acount for the diference of the injector constant. Any tuners out there have an opinion on this one? I have heard that some tuners don't change the Cyl Vol but mine does not match a 350 either. I think it comes out to around 366 Ci with the 744.15 value.

Ok I found a better formula that even works better using the conversion calculator here
http://www.nettam.com/convert.html 383 Ci = 6276.2593 ml /8 = 784.53 and that is even further off
Edit 2,
Ok that was a bad idea it screwed everything up. I went with an injector constant of 34.5 and it was still way lean so I just droped the old bin back in and all looks good again.

Especially on a MAF system. They are so intolerant of vacuum leaks that you'd notice it right away in things like idle quality, throttle response and off idle hesitation.
