It cuts more fuel then possible for combustion... So basically it is a misfire, not a lean condition... No detonation/pri-iggy
Lots of Supra people install it because for high boost applications it can react VERY quickly, and cuts power effectivly without using fuel cuts that cause a lean burn...

Fuel Cut
The idea of cutting fuel to an engine sets alarm bells ringing in engine builders, as they all know of the potential disaster of a high revving race engine running lean. Running in a lean combustion mode will elevate in-cylinder temperatures very rapidly, the denser the air/fuel charge, the more heat the lean burn can generate. Therefore it is vital that a fuel cut system will not cause a lean burn.
The simplest way of preventing a lean burn is to remove more than 50% of the fuel from the pulsed delivery.

I'd buy a 3.0 rear in a heart beat... You'd be able to stay in gear longer, and use more of your TQ instead of having it spin off @ the wheels, or be wasted with time shifting...
Depend on your goals...I think taller gearing would be nice for a street driven car...but personally, the current gearing will allows our cars to run to 185mph (RPM limited), and thats tall enough for me.

And to think I laughed when a local tuner told me the "supra guys" were running 700, 800whp and were begging him for more HP. How long before more of us Z guys are clamoring for the same?

You would be making close to 750whp at that boost level.

i can see guys getting 800whp and something like a 1.5-2.0 final drive where you can do something like 0-80 in 1st gear then people start wondering why they got a manual in the first place if they hardly ever shift their car.

First I have to sell an investment property and see what my end of year bonus is like, cause there are other things I want first. Anyway, if I go full standalone with traction control it won't matter how high I go with whp cause I am going grip like a *****!
MOTEC UNIT 6,000-10k. The best thing about it it can onl be programmed by the orginal owner
