Thermoquads are all junk, and they run like chit. Hard to keep a tune, don't do what they are supposed too when you tune them. Parts need to be made to fine tune them. A/F Meter numbers mean jack-**** when trying to tune. You have to resort to throwing fuel or air at it to see if it picks up or not. On top of all that, a six-pack picked up 3tenths in the car....
