I got a jb4 g4...can I run e85 without upgrading the Low Pressure pump?

You can run a mix of E85, not 100% E85. I'm running approximately 25% E85 (12 gallons 93, 3-4 gallons E85) right now and I just put my JB4 in about a week ago. No complaints so far.

yes usually your safe up to about e40. on rare occasions some people get a way with e50. so through some in and enjoy

I'm going to try that...on Map 5 right?

you can do map 7.
i run half a tank of E85 no problems
it will however bring out the weakest link in your fueling system.
if your coils, sparks and injectors arent in good condition you will misfire.

i have run 100% e85 on the stock pump and it was fine on map 5 not reliable on map 7. would be fine if i had a walbro upgrade.

i generally run somewhere between e60-e70 with no problems.
