In cooler weather, I can be at a stop and then go from idle to full throttle with no problem. In warmer weather at a stop, I bring up the rpms (mid teens) and then let go of the brake and go to full throttle at the same time.
I am currently using my wideband to retune my secondaries to limit the fuel on the secondary pump so that I do not need to use my brake from a stop to go to WOT in warmer weather. I am finding out that my combo does not need the full 30cc's from the secondary pump even when using the smallest volume pump cam. I am adding an air gap between the secondary pump arm and the cam and that is keeping my cruise to WOT A/F ratio where it needs to be. I am still working on this to lean out the idle to WOT though. I can still mash it at idle in warmer temps without a bog, but it is not as crisp,,, yet.
