I'm using 880 cc/min low imp injectors with out the flyback board as well. No problems yet, I've done quite a bit of driving a loging after installing my wideband last week, but I still need to tune my VE map. The MSNS-E code has a bug and I get a rpm blip everyone once and a while. Nate, you seeing this? Watch your RPM's at idle in Megatune and see if it jumps way up, or if your peak on the MT Tach is pegged. I'll be working on the MS tonight, but I don't think I'll be able to get any tuning done cause It's snowing again. :(
