were the injectors new? perhaps one is sticking open? or possibly there is a problem with the wiring to the injectors.
does the iscv work as it should?
I know many who un MSD software etc with no issues and had hoped to do the same, as I have said to Stu I am not blaming the chip or anything they have done but would very much like to sort it out!, the injectors were supplied at the same time as the chip and are new siemens injectors.
ISCV has been set up and working fine, once I had renewed the seized adjusting screw that is!

Without knowing your engine itself maybe someone else has made a mod you are unaware of, which is throwing the chip/fuelling out.
The quickest and cheapest way by far is get all your mods done then take and have it live mapped, it will be perfect then, each tuner likes slightly different things however, but most of the big names do a good job, msd nms to name but a few, you seem to have covered all that would normally be suggested, but a live map will find out the problem for you.
If you were planning lots more mods in the future I would seriously consider going aftermarket ecu, as I did best thing I ever did, can now get over 400 to a tank, that was with 200,937 miles on the engine, now stripped for rebuild, emissions were 0.97% CO, 137ppm at idle on a T34, with GREY injectors, off boost power was awsomely improved with live map, picks up from 1400 full boost by 2500.

I fully appreciate the pitfalls of chip tuning and if money were no object with this car then I would of course look down the live map or alernative ECU route but having done the whole Motec, Autronic ECU with previous cars I begrudge spending that sort of money on a car that comes out once a month fr a quick hoon and then gets parked up again for the rest of the month!!
I also appreciate how difficult it is to remotely tune a car via a generic chip and I went in eyes wide open and would accept some niggles but the fact that the CO is so erratic is not really down to a "generic chip" thing its more of an actual fault but having checked everything I was just wondering if something else could cause it and I have miseed it off the list of checks!
I also know a live MAP would sort the car but again begrudge chucking X amount on a chip only to find out after a few miles its not suitable and becomes bin fodder!
As explained to Stu I dont have the time or opportunity to escape to Blackpool for a day until much later on in the year and every other tuner I have spoke to can't work or won't work with MSD chips due to encryption etc so this leaves me in a situation where I have to figure out as much as I can on my own!
Cheers
