$375, bought off another user on GTRCanada which was used lightly on a RB26 without issues.
Good condition with everything in the picture needed to run. You can download instruction manual on the internet.
I haven't used it myself as I am going AEM V2 next year which has a boost controller feature in it. Just looking to recoup (less than) what I paid for it.
PM with your email / cell to further quicker discussions.
Thanks
