I have a vortech with DW 600's and walbro. I have the Utec and a map sensor.

I have the utec running the Map and parameters from the intake/exhaust basemaps on the turbo xs site; I changed it to -20 in the 0% load column. It starts and runs fine in closed loop mode, but if I hit the gas it dumps fuel, sputters and runs super rich.

I tried the base turbonetics 550, but it idles really rough and stays at around 9.7 AFR. Anybody got any better maps or ideas to get this thing 80 miles to the tuner?

 

search the forums i once found a base map for the vortech with 650 cc injectors...
