    I'm considering getting a remap on my 99' Disco Td5 (head says stage 1 tune and heart says stage 2 or in that vicinity). I've already blanked the EGR off, and removed the centre muffler for a straight pipe and got silicone hoses. Now I'm going to look at other modifications before I go for a remap which include: Allisport intercooler, Allisport exhaust manifold (and ill put an EGT gauge in as well) and if necessary and uprated radiator. Other than that is there anything else I would need to do for stage 1 or 2 tune? And even though this has been answered a million times, what are people experiences with tuned Td5's? And who would you recommend for a remap? Cheers Guys :tea:

    Pete bell that owns bas at York is the boy when it comes to mapping 5s . it's a live map not just a generic map that most places offer . get yourself there he's a really decent fella

    What mileage had it done out of interest? Has it done a lot of hard Work ie heavy trailer work etc? As in really tuning up a high mileage engine may send it to the grave before it's time lol?

    I went for big cooler hybrid turbo running 28psi and a real savage map with torque limiter smoke limiter and rev limiter all set off the scale on a 99 defender with 130.000 on her she's done 170 now and no problems other than exhaust manifolds and AFM's

    Ive thought of a camshaft but I want to keep it to as much of a budget as possible (is that actually possible when modifying these engines?). I think ill put a high lift cam in the 3.9 v8 though.
    As far as mileage its done 260,000kms (and I dont think its done much if at all any hard work like towing) but it's as strong as an ox and pulls really well - I just want more lol. And in comparison our Defender Td5 which tows a lot (including a 3.5 ton boat) with half a million K's goes as strong as the day we bought it.
    There might be a BAS bloke out here, ill have to check and if not surely Alive tuning or IRB or something would have something in oz?
    what do people think; stage 1 or stage 2? because surely the engine would last longer on a stage 1 in the long run.

    stage 2 is a similar map as stage 1 but with a big intercooler,
    stage 3 as above then a variable vane turbo

    So really stage 1 and 2 and even 3 are all the same sort of map but the only difference is that they are programed to make use of a larger intercooler or vv turbo which is where the power gains are - is that sort of correct?

    seems that way to me, obviously if your going to be fitting a larger intercooler or vvt, do it before the mapping, a stage 1 map is still a good mod to make, with noticable gains in power and torque

    Okay then that's interesting then. I think what I'm going to do is go for a stage 1 first because to be honest since fixing up that surging problem I had, I've a couple of times been impressed by the power even so though, there's some hills I would like to be able to accelerate up lol. Also I'd like to know that id be doing it reliably especially for the distances we cover over here. But I'm still open to a stage 2 in the future.
    Anyone have any experience with stage 1 tuned Td5's - what are the like?

    Makes you wonder why they didn't do that from the factory?
    So with a stage one, will I really need to do any underbonnet mods (I'm thinking in particular the exhaust manifold because of potential warping) or should it be all good as standard?

    Ive not had any probs with warped manifolds, some people seem to have though,
    better to get rid of the egr, and make sure its all running as it should, then you should be good to go with the map

    I guess if you were doing heavy towing or flooring it constantly you might warp a manifold - I think as cheap insurance an EGT gauge will be going in.
    The EGR's already gone and its all running sweet, my only problem is trying to find someone that remaps Td5 ecu's in oz. Theres a lot of plug in chips over here, but from what I understand, these aren't favourable for Td5's?

    I have warped my manifold since having the stage 2 remap, the main difference I noticed between 2 and 1 is that 2 gives me more power at high revs where as the stage one used to fade out at high revs, bit more smoke and much more fuel used. if u have manifold re surfaced it should not warp again though as it has already done what it wanted to do.
