I've had several of those sent here. They can be effectively calibrated and actually work quite well. I've had them on the dyno and followed up that testing at the track.
We ran within .02 seconds of my 1977 Pontiac q-jet, within .5 mph as well. They drive fine on the street, but the calibrations are WAY off what a standard unit would require. Seems to me it would easier to just replace the casting with another $30 unit than to go thru the steps required to put boosters back in it?....LOL....Cliff
