please help! miss-firing
just had my DC2 GSR turbo'd with a TD04, 3" exhaust w/dump-pipe, custom manifold, larger injectors and front-mounted intercooler. the system is being run buy an EMS stinger ecu and is currently getting a thorough tune. whilst tuning, we have discovered that as the turbo comes on boost, it misfires. cars stutters and is generally running like a *****.
changed the spark plugs, still nothing,
changed leads, still nothing
change the computer, still nothing...
injectors are totally new...
what else should i be looking at??? what other causes may there be...?
please help!!!

Start with spark plug gaps, try around .025 and if the sputter is still there it is probably your coil. I had the same prob today its is already fixed. Bad MSD coil 
Also make sure you are using map as load. I have tuned a couple ems systems and for some reason the it had TPS and MAP as load with SOME base calibration files.
