With today's high price of gas, and a good possibility it's going higher, I was wondering if a dual boost controller would be useful.

My 87 4Runner turbo specs 87 octane. That's with a 7psi factory boost limit and no intercooler.

The TEC (T3/4 combo) I've installed runs 9psi, and I hear premium is recommended, and that 10psi unintercooled is still safe in this application. The ECU has an 11psi boost cut that cuts fuel anyways.

I'd like to be able to run 87 most of the time, and premium when I want more power, preferably at the flick of a switch. I'm looking at the BoostValve 2-stage valve.

I get that timing wouldn't necessarily be compatible between the two, but if I leave timing where it's not quite pinging on 87, I think I can live with the reduction on 91 (well, until I figure something out).

Future upgrades will be an intercooler, and disabling/bypassing the factory fuel cut.

The big question - is this goal a waste of $$? Or would it work reasonably well?

It's a waste of time, do something else
