I've got a TD05 20g on my car and currently have an Evo IX pump installed. It is NOT rewired. I'm not sure of the signs showing that I'm running out of pump, but it seems to lean out every now and then while doing a pull.
Mod list is as follows:
TD05 20g set at 20-22 PSI
VRSF FMIC
Evo IX Fuel Pump
950cc injectors
Full 3" exhaust
EcuFlash
For diagnostic purposes, I currently have all fuel cells set to 11:1 AFR to make sure my wideband is reading correctly. When I do a 2nd-3rd-4th pull, it often spikes to around 12.5:1. However, it usually stays right around 11:1 (+/- 0.3). Does this mean I'm out of pump? Is the Evo IX pump enough to support a basic 20g setup?
Also, if I rewire the Evo IX Pump will I need an AFPR? Any input would be appreciated.
Lastly, does the Walbro 450 whine as bad as the 255?
Thanks
