It sounds like whatever uprated MAP sensor you have isn't working properly, and/or the piggyback ECU (what do you have ?) isn't working properly (bad connection ? fault ?). So instead of lying to the stock ECU, the stock ECU is seeing too much boost and so the car is going into limp mode.

ok, so if it's an e-Manage blue, it hasn't got a built-in uprated MAP sensor. So you must have a separate one somewhere ? I've got GReddy's own uprated MAP sensor attached to my e-Manage Ultimate.

Have you got an AFR gauge so you can see what's going on there ?

I strongly recommend getting the AFR gauge connected up ASAP. Mine has been absolutely invaluable, especially when anything weird happens, to help me see what's going on.

Going back to your mapper sounds like a good plan to me. Are you planning to swap out the e-Manage blue for something with more capability ? e.g. an Ultimate or another piggyback ECU ?
