ok no worries then.. just make sure when you get your loom done and also tune that the tuner knows what they are doing... As previuosly stated there are a lot of good tuners out there but there excelence/expertise seems to stop at only tuning a standard car to something better... as soon as it requires either a blank ECU to be tuned or even changing some of the settings in there that are often left standard they are baffled. We have be testing our ECU's on 3 particular setups (2 x Boats and S/C Patrol) for quite sometime and now have it all sorted (was very frustrating/painful to get to this point)...

guess main thing out of this is make sure the tuner is clued up on all the tricks E38 and LS1 are 2 very different beasts!
