E85 tuner

He is saying if I run straight e85 I will kill my pump asap. He agreed the 42's on a stock tune would work. If course this all could be an upsale.

Yeah, it won't kill the pump. Just make sure you change the fuel filter after switching, and you'll be fine. Get a caspers or racetronix rewire on there as well. A stock pump will supply enough fuel to get you below a 3.0 pulley in most cases.

you take that risk. its so close to max it may as well be maxed out.

As I said, 85-90 idc shows that there is a lot of fuel left.

42's will support 340 chp on e85. So, unless a stock engine magically gains 100hp from just switching to e85, you are wrong.

I ordered a Casper hotwire kit, voltage booster, and 4ga alt power cable.

it rained here last night, just yesterday i finally got my tune set up for real 50/50 meth, went food shopping and didnt even floor it and it busted the wheels free at 60 mph, wet roads of course, all i did was give it enough gas to pull out and pass the guy a head of me, never made it past him. its never done that before. from a stop on wet roads, theres no more being in a hurry, cant even take off if you give it more then say 10% throttle. then once moving on local streets 25 mph ish any extra pedal made them spin with way to much ease. cant wait for dry roads, maybe i can find one of them wrx things while im out lol

Gap one for me cuz the one I went with from a dig handled me.

I used a stock fuel pump all the way to a 2.6 with E85 and 42's, but it was leaning out and the pump wasn't cutting it. with the upgraded pump, I'm at 80% duty cycle and that is the highest i want to go. I do feel like i'm the exception to the rule as I live at 7000 feet elevation, so the air is so thin up here that I don't need near as much fuel. I also run water/methanol so I get more fuel headroom from there.

you can get away with not using a tuner with E85, but in my opinion you should use one.
