broquet boostmaster 40 and top fueller

Actually don really.........

I have the B40 in the car and it was indeed smoother after installation and there is a little fuel saving.

But based on fual saving itself dosen't justify the purchase as I'm probably getting about 3-5% saving and if u work that out against the price of the B40, then the return rates is probable about 7 years.... yawn !
