I am working on building a 1000whp twin turbo car using the huron speed kit. I want to run separate tunes so I was wondering how hard that would be. I got a friend that has a pump gas tune and can flip a switch to turn it to a e85 tune. I want to use a boost controller to change psi for street driving or strip. I was thinking two tunes on pump gas one for 6 psi for daily driving and one that takes pump gas to the limit. then another tune for e85. I will be spraying meth of course. I know I will need a speed density tune. do I need a aftermarket cpu? is this possible to do? I will have speed inc do my tuning

Some companies will modify your pcm, I have a dual(2 tune) 411 I want to get rid of... But contact pcm calibrators and see what they say

ok thanks for the info. i had a friend tell me he did his with a boost controller that saved different tunes

You can save different boost maps in some controllers and select which one you want to run, thats not a big deal. As far as flipping a switch for E85 or pmp gas, its not that simple with a stock pcm.
