His car has made me go out and get a LS car and have some fun.I had 346rwkw's in my Ford out their but it just wasnt me,I need the V8 influence lol.
The reason for his fuel economy is that the tune was rather lengthy in setup,my miss's family owns/runs the dyno centre so it had alot of low speed tuning done also.Cam is over 600thou lift.He is able to let 5th go down to 50 and still pull away without any chug making daily driving alot less hassle so to speak.
He works in the mines and is single so he would buy a servo to keep on board if he could.He hardly ever gets this fuel useage numbers though.Like you said,you dont own the said vehicle to worry about fuel.
