disco 300 tdi flat spot

<< < (2/2)

Disco-Ron:
replacing the hoses does very little, if anything, but whilst i was having the intercooler done, it seemed wise... also, the top hose doesn't now have that sillt egr thing in it...!!!

I still have the cat in my exhaust, but not for long!!  and even with it, i can still drop the revs right down and still accelerate...!

I just noticed all the threads took into account the tuning mod changes that could be made,

Another point is do you have large tyres as this can also result in a large flatspot as well as reduced performance.

I think my 300tdi has a flat spot around there as well (when it is wearing its mud terrrains) but not as obvious when
wearing its road tyres due to the reduced rolling resistance of these tyres.

I have fitted large intercooler and have tweaked diesel pump and recently rebuilt turbo which has helped things

Does your engine rev out easily to 4000rpm? as it could be an injection timing issue.

Timi  :cool:

Disco Matt:
To be fair, mine on standard size A/Ts always had a tendency to bog down when pulling away, still will on hill starts. It revved perfectly, but was just a bit gutless at low revs.
