Jacobs mastermind ?

I have a 454 in my 69 that makes 450 rwhp and 470 rwt. I am going to do some head, intake and bigger cam work to get to 500 rwhp (Goal) I have a sportsman fogger plumbed into the intake manifold. I am running a 150 shot now. I was looking at the Jacobs mastermind and wondering if anybody is using it. I like the idea of rpm related nos flow. I would then run an rpm related 200 shot. What concearns me is the pulsing of the system. It seams like on a direct port injection system like mine the pulsing could be an issue.

Any real world experiance

I would go with one of the other controllers over the Jacob's Mastermind.

It is a piece of junk in my experience.

Thanks Vette 92, I read the post, what do you reccomend. Do you thiink the idea of rpm related flow is not doable.

Unfortunately there are no other controllers that do RPM dependant activation that I know of. Both the NX and NOS brands run off of time based activation. The NX controllers are very nice though.
