Default Won't start immediately after run

I'm having an issue when I shut the car off and almost immediately start it again (like at a gas pump). I'll have to put the gas pedal on the floor once and it's ok but I know something isn't right. It could sit for months and start on the first crank with no pedal, it's just in that certain situation. Possibly a rich condition right now, could that be it?

What? You put gas to floor and then let off and it runs? Are you turning it over at this time? Go to SBFTech figure it out.

Actually, I'm running 24# injectors with a ported stock MAF. I have a C&L for the 24 squirters but it runs very bad with it. Yes I disconnected the battery to reset computer. I think it's for bigger injectors. I recently ported out the actual metering hole where the MAF filaments set and that helped. I guess it's all about tricking the computer. (Still need a correct MAF)
