changing dash for diff ratio

[maccavvy]

Hey guys
looking at swapping the 3.46 out for a 3.7 or 3.9 what do I need to alter the dash.

done a bit of googling that says tech 2 can do it.. does vz cluster mod do it too ??

go with the 3.9 , ferret may know he's good at those sort of things

Its actually done in the ECU so you would use a tuning package like Efilive. If you can find someone to do it for you its will cost you the price of a license to reflash the tune with the updated final drive ratio.

if I could find a 3.9 I would ive located a 3.7 though .

ive read tech 2 can do it. or snap on solus .. should be cheaper than efilive too surely

I did mine with HPTuners, I've got a licence for 04 and 05 5.7 cars if it helps.
