I havent been on here in a long...Dyno jet just came out with a new product that will allow me to adjust my VE table and such. My motor is a ported head,935 big bore and big cams. I have a terrible off idle stumble, when you crack the throttle open quickly (race it so happens frequently) that I cant get corrected with my dynojet pc5. I've been trying to figure out how to tune the VE table with just the map sensor and a WB02 sensor. A problem is that the exhaust is so short on these that they are notorious for air reversion and thowing the WB02 reading off at low RPMS and idle. Can someone possible direct me to a good write up on how to do this or if its possible...

Thanks Shawn
