Can I run this they dont have E85 in Panama and I wont use the full duty cycle?

Yeah you wont run out of fuel. They will support 600whp on standard petrol and one pump maybe a little more. I ran 1000s to 606whp and was just out of fuel on a single modded 255.

I'm running those two you listed right now. I however have a dual map tune. You should be fine.

might be a little tricky to get idle correct but it will work

They idle pretty good actually, better on bigger motors.

That's what I've been running on.

My idle is fine....Warm starts are an issue for me for some reason (still too rich)....

+1 my warm starts are a little funny too. only sometimes though
other then that, car runs great on the 1200's

Also running them with occasional warm start issues

eitherway my pump is very old like 3 years so I was going to change it out I just dont want dual I might try the new DW pump
