Ivan,Saab 9-3 1.9 TiD

Hi Dan, Have left it a while to thoroughly check my findings, and am very pleased - this last tweak, along wih the K & N filter means I am now locally on 44 to 46MPG, on a run 57 to 60MPG, the torque does not seem to be affected for it still accelerates in high gears from 1200RPM, and lots of torque by 1500RPM, but the even more surprising result over two longish but in traffic journeys tugging my 1500kg caravan gave me 36MPG, excellent. All on a tank top fill basis so no computer optimism included! This setting certainly suits the engine. Thanks and regards,

An excellent bit of kit, fit and forget, does what is says on the box!
