The tyres i have fitted are 235/80 r16 i reckon i have gained about 1.5 inch or so in height think the standard size was 235/70 r16. Thanks i will buy LRO tomorrow.

Thank you all for your help, will try a de cat pipe was looking at it earlier it has a stainless exhaust but the cat is still there so i am ordering a de cat now. Does anyone think that the bigger tyres i have fitted may effect it as the rolling radius is much bigger?

Thanks i will have a look, Just seems strange how its just gone this way recently.

Yeah thought about that i was following a mate who said he did'nt go over 70. I have fitted some slghtly bigger tyres recently but i would'nt of thought the would make that much difference.

Hi, i own a disco 1 300 tdi when i bought it a couple of months back it would quite hapily do 80 to 85. it has seemed a bit slugish lately and will now only do just under 70. I have replaced the lift pump, fuel filter intercooler pipes, cleaned the sediment trap, replaced air filter with a K&N...

Are these questions i should be asking lol?

Hi, i am new to the world of landrovers been scaning this site and found loads of useful info so i thought it was about time i registered and introduced myself. It really is a great site. I am from lincolnshire and have a discovery 1 300tdi which i have owned for about 2 months now.
