So I am seriously considering decreasing boost and going back to pump gas tune on my car. The E85 makes silly power but for the street its just too much. The car has a full MM suspension ( no drag car set up )

So my thoughts are change spring in the gate to say 7 psi and use the E-boost2 to up it say 14 psi.

Only get 91 Octane here so I will be octane limited. Now I need to find a BS3 tooner in the area ...

Deep down I have considered removing the turbo and swapping to a high rev cam and beating it on the streets NA

I want to simplify things, 35 miles to get E85 is just a PITA currently.

Anyone care to comment?

I think it's a solid plan fwiw. I've never had as much power as you're making. I can imagine its kinda a pita on the street and driving that far for fuel would be tiresome. Don't blame you for wanting a friendlier street tune. You could make me a good deal on that turbo setup and I'll take it off your hands

Crazy hp is fun but not so much useful sometimes. Detune it and still have fun but do not remove that snail!

35 miles??!!! ...there goes fun out the door. As soon as you detune it a gas station with E85 will pop up around the block, that's how it works

wonder what it will do on say 14psi on 91 octane I dont want to run meth either.


Also will I need to swap out the 120# injectors or will they be ok

I think I will run it around on the spring with the E85 tune for a while once spring comes around. The spring was making about 12psi if I remember correctly.

Get a 55 gallon drum for the e85 and make a trip to fill it when needed. I dont know if i could trust pump gas at 14psi on an expensive motor

good point, where is the comfort level on 91 octane? 10?

at 11 psi on e85 it made 611 rwhp that is still silly for a street car/toy

This is a good idea. I can dial back the boost and keep current e85 tune.

Ran meth before, it does work however I am not looking to do it again. I will give the lower boost e85 idea a go.

was the big stuff already tuned all the way though the map? if you stay on E85 and just go down on boost nothing should need changed unless it needs cleaned up at that point

yes its already tuned on e85 via the BS3

it is kinda funny to think lots of guys do a mass air upgrade, then when you do stand alone you go back to a speed density set up.


dumb cars.

you can use a 55 gal drum - them make dollies for them as well as attachments to easily lift them with chain. If I'm not mistaken, you have a car lift, correct?

as long as it'll lift high enough to drive the bed of a pickup under, it should be ok, even if it only lifts a couple inches over that you can just drive out from under it.
oh, and something here would help
