Please note this an average guide across the rage as there is many different gearbox’s and rations. 1.9D and 1.9TD in our opinion it’s best to get 0.658. This will save you 500 revs. The only exception here is if you tweak the turbo and fuel to get power gains up to 90bhp and with this you can go for the 0.622 ratio.
Example At 70mph you would expect to achieve 3000revs with the 0.658 upgrade. (Current revs @70mph 3500) At 70mph you would expect 2500revs with the 0.622 upgrade. 2.4D and 2.5tdi in our opinion it’s best to get 0.622 Example At 70mph you would expect to achieve 2500revs with the 0.622 upgrade. (Current revs @70mph 3000) This upgrade is also good for all petrol engines. The drop in revs is different for each engine modal but a good average is 500 less revs at 70mph than you currently have.
