22nd Jul 08 DEAR ANDREW JUST WANTED TO SAY THANK YOU FOR ALL YOUR HELP AND WHAT A BRILLIANT PRODUCT. WE HAVE BEEN AWAY ON A SHORT BREAK TO GREAT YARMOUTH. I DROVE THE CAR AFTER I HAD FITTED THE GREEN UNIT. I HAVE MOVED THE SWITCH TO “A” AFTER TEST DRIVING IT IN THE OTHER POSITIONS. I CAN NOT BELIEVE THE INCREASE IN THE HORSE POWER AND THE DIFFERENT IN THE MPG IS FANTASTIC. WE DID 136MILES TO GREAT YARMOUTH AND RETURNED 44.9 MPG, 34MPG WAS THE MOST WITH OUT THE UNIT FITTED. AROUND TOWN SHORT JOURNEYS 36.6MPG INSTEAD OF 26MPG. I WAS WONDERING IF I COULD MOVE UP TO “B” POINT WOULD I GET ANY MORE PERFORMANCE, MPG. THANKS AGAIN MATTHEW WHINES
