Hey Ray do you have a 3" exhaust? if so do you have a dawes valve? Just wondering if I would be right to whack a exhaust on without a boost control on a crd or is it a must(already have a steinbauer installed) ?I've got a DPChip, but made an interesting observation recently that may well be applicable to Steinbauer. When I originally installed the DPChip, I went progressively from the standard middle setting (5) observing how the engine performed and what degree of smoke was present under heavy load/acceleration. Whilst the power felt to be increasing, at 8, it was blowing smoke far too much to tolerate, so I backed it off to 7 and left it like that for the last 50,000km.
Recently, I finally installed my ETG gauge and decided to see what effect the various DPChips settings had on exhaust temps. As I progressively dropped the settings back to 5 and then even 0, the exhaust temps stayed pretty much the same except for, from memory, a slight increase at 6. But what I really noticed was the fact that the Patrol had much better performance at setting 5, compared to the previous 7 and ever since leaving it at that setting, it's just felt better.
I think as the engine has bedded in, there hasn't really been the need for the higher setting and, if anything, it's been over-fuelling and the ECU has adjusted things to compensate, with no major increase in power. So if you're installing a Steinbauer, try all the settings and at some point in time after the engine has bedded in, try the setting again and see what you get.
I currently run the standard exhaust. I queried Taipan twice about putting on a 3" exhaust with a chip and not installing a dawes valve and all I got from them was crap, wouldn't give me a straight answer. They kept insisting that when the 'MAF fails...', and I kept asking 'But what if the MAF is working fine?' Probably just covering their ar*e. George has a chip and a 3" (locally made) without a dawes and it seems to run fine. I reckon that the CRD ECU is able to control boost so that you don't need a dawes.Hey Ray do you have a 3" exhaust? if so do you have a dawes valve?

I hope the guy running the dyno wasn't trying to get air/fuel ratios the same as for petrol; a whole word of difference between diesel and petrol.I had my 2007 CRD on the dyno after fitting a Steinbauer and a 3" exhaust from Scotts Rods.
I had it at 100% before,but the dyno figures gave a too rich fuel/air setting,so we set it to 90% and then to 80% which gave a good fuel/air ratio,according to the dyno operator,and lost only minimal power.
Everything goes well and no problems.
