Yeah, should have been a bit clearer in my previous post - again, I haven't yet got my EGT monitor in place so this is all based on others' experiences.Quote:

May simply be that remap improves EGTs in net - someone with a standard map with the EGR disabled may be able to provide a bit of data?
Best chance would be Bruce Davis of Davis Performance Landys at Annangrove.Quote:

You should be aware that remapping will cause issues for warranty work, and will also cause issues if the dealer reads your module or installs a software update. This wasn't a problem with the 2.4, but is stopping most from doing it to their 2.2's if still in warranty.
Out of interest Pickles are you keen to get this done on the new truck? I mean I know all the benefits etc. but as a fellow MY13 owner I'd be very reluctant to do it before my warranty expires.Quote:

No, it'll be a while, if ever, before I touched the engine, but I do like to suss out what's available. In the UK there's squillions of options & expert shops etc, but very few in Aus.Quote:

Cheers, Pickles.
I haven't seen the Puma engine code, but every other engine I have shuts the EGR at full throttle.Quote:

Yes I guess that's exactly what you would expect it to do thinking about it.Quote:

To shut-down the EGR you need to get into the ECU and find the bytes that switch in on/off. It's a job for a sharp tuner. Lots of blunt tuners around who don't know and try flattening maps etc with more work and not as good results.Quote:

Yes I know, I said I meant the variable geometry turbo. Over here the upgrade turbo is called all sorts of different things, by all the different companies who supply.Quote:

Increase the bore / stroke ?
Well LR decreased one of them going form the 2.4 to 2.2 andthe 2.2 has slightly more power, go figure.
The cheapest solution for you is to drive a Tdi for a while and then get back into the Puma it will feel like a rocket ship !
During magazine reading I noticed that the following companies offer "tuning" for the Puma, evolve technik, tunit, dms automotive. (All small case as per website!)
Don't know anything about any of 'em, except I reckon they'd all only offer a "generic" tune, not something particularly tuned to your particular vehicle, some of them may also be that "piggy back" style box that tries to "overide" the standard ecu?
