Hi, I have joined forum but awaiting confirmation email. Quick question. Just bought a 90K mile 2001 4life. I was wondering what, if any, difference the ralliart or other tuning chips have on mpg. I am road user only and drive light footed around 55mph. Would the upgrade help at these speeds or, as I don't NEED more power, am I best leaving well alone. Gbn

To be honest I dont think the chip makes much difference with the fuel consumption on these trucks. If you wanna save a few pennies use some veg oil in the tank, keep the tyres pumped up use road tyres too

I'm not 100% convinced that the chip works on pre fly by wire trucks ....... do you know @123hotchef ?

no need for it on a pre fbw mate no there is no ecu to plug it into

Ah, when did classic shape change to fly by wire? Truck on road tyres already, loving it, lovely old thing to drive...not much difference in diesel price to vegoil now is there? Thanks for advice, will post more once approval given .Gbn

2001-2002 was the change over take a look see if you have a cable operated accelerator and fuel pump
