Do you want a G5

you'll be able to use the new ISO boost control as well.

My friend is selling his. It is already wired in the harness, along with NLS/2STEP, and the USB.

There is so much the ECU can adjust for. Your tuner was referring in that case to timing advance.

With E85 it is not only timing advance but also, you need to tune fueling as well. With COBB it is very simple, you change your fuel scalars and you're set.

And yes, it does give huge power gains vs running pump gas. It is also much cheaper than race gas.

Dammit, i knew i should of kept the cobb ap.

Why did you let it go? it gives a lot more flexibility than your current tune. Just curious

[335twins]

when i flashed the car and send logs to cobb they told me i should change it to their sport 91 octane special map and i was still getting bad logs so i decided to sell it and get a custom tune, but now i think it was the car and not the tune, i had new fuel injectors put in by bmw, spark plugs replaced, chemical treatment and the car is running much better now. I still have some hicups when i get on it, but i think the tuner will figure it out once i drop it off to get it retuned for FMIC and downpipes, well once i install them.

Hardware definitely makes a lot of difference!

Get COBB used, install at least DCIs+intercooler, put it 50% ethanol, PTF tune and I promise you will be surprised.
+ the custom tune will account for your hardware variances (WG stiffness, among many others...)

I feel like that too and thats when I use the nitrous on special occasions when i want to feel a rush! lol

With e85 its a conplete other level alot faster try jb4 or cobb e30

Procede Flexfuel with straight e85. Makes other stock turbo tunes feel weak

For somebody that just wants to run 50/50 93/e85... what is the difference between the flexfuel kit and the 50/50 aggressive mapping? I don't feel like I really need the kit...

Not sure if serious??
z06 has 505 crank...he has 500 wheel lol, he obviously has mods on the car...

The difference is 20-30whp

Do what i did:

Drive the work truck for 2 months. It was a Toyota 4Runner with 250k miles, no exhaust, and cranked on the 2nd try.

Oh, i love my car.

i didnt say that he doesnt? like i said you dont need much. im sure you can figure it out...just an intake and exhaust will make those v8's net 20-30hp.
