Dual maps?
On an evo 8, 400awhp from a stock 9 turbo on 91 octane pump gas is impossible. 93 octane is a very slim possibility, but you're going to be at risk of engine failure with a bad tank of gas. E85 on the other hand is possible on stock 9 turbo. I've seen some 400 awhp on dynojets and Dynopacks. No way on a mustang dyno (without any silly correction factors).
Re I sent before I finished lol I went to get the car tuned after sorting out leaks and other underboosting issues so during the tune @20 ish psi it made or I found a nother boost leak so we called it a day I fixed the small leak and he had a baby and was on vacation and now I have a 9 turbo to install.. I still made 360 awhp on pump at 21psi with small leak. So my plan is check on pump and install 9 turbo and go to English. I wanted the 2 maps on the button for cool factor and for when I got the gf in the car lol. I enjoy a fast daily I'm am shooting for 400 awhp on pump with the 9 turbo.
Boost controllers are not affected by fuel. For E85, you need 30% bigger injectors to burn same amount of air than gasoline. With E85, intercooler isn't as important since E85 is cold and cools air down (91/93 octane gas will need that upgrade). Are you sure you have a FWD Evo? If your center differential isn't working, I would think more power goes to your front wheels since there is less things to turn. Your tuner should have seen the dyno screen showing powers at each wheel and would know if rear wheels are not turning.
Mine to switch maps i have to turn on the key and step on the gas.when i see the check engine light flash i know i switch maps. I had always heard to in order to tune dual map needed bigger fuel pump well at least e85 compatible boost controller and injectors (over 1000cc) i have pistons rods all valve trained intercooler cams injectors fuel pump intake boost controller pretty much it. They asked if i wanted aggressive tune or normal. Since its my daily i said a normal tune. I made 370whp on 85. And left as factory on 91. I messed up there. I should have asked for agressive tune i could have just taken it easy. But then again not sure if it only made 370 cuz my tcase not working and only my front wheel spin not my back ones meaning i got fwd evo
