Hey Steve,
Did you get the reply I sent to your PM the other day? I sent it but the post send page didn't load afterwards. :(
Thanks for those suggestions!. Yep I disconnected the battery to install the intake, and the week after had it disconnected a few times while I tested and installed the RSM and G-Sensor.
My butt dyno says the same...ie there's a big difference, which is why these dyno results including the AFR is so puzzling. I'll do a power run with the RSM tomorrow, reset the ECU, let the ECU learn the fuel by flogging it, then do another power run to see if there's any difference between the two values. Damn and my tanks almost empty too!!!!.....BP here I come to be robbed on a tank of ultimate! lol (ouch damn holiday fuel hikes ;) )
I'm very curious on the mixture running so rich.......very curious indeed. :(
