Hey guys,
2008 Silverado 1500 4.8L (non-flex fuel) w/ trick racing turbo stage III + AEM WBO2, everything else pretty stock.
I recently installed 95 lb injectors from Fuel Injector Connection (because my stock injectors were running 110% duty cycle at 3 psi!). I used the old double stoich, halve the IFR trick and wrote that. When I try to start the truck, it turns over, seems to start for a second, then dies. When I stomp on the throttle this keeps it alive for half a second longer but still dies (I wish I had a cable throttle rather than an electronic throttle, I feel it might stay alive longer).
I reverted back to stock stoich settings, maxed out the IFR table at 63.5 lb and now my truck at least runs, just really rich.
I haven't yet tried scaling the long way (especially because my VE values are expressed as coefficients, and haven't yet converted to values to use the custom 2 bar OS available), and wanted to know if someone could suggest why the double stoich/halve IFR didn't work?
Any help would be great, thanks!
