Help Bad Miss Fire

[mang 3]

in my 205 iv put a 2ltr 8v turbo out of a citroen xm im having prbs with the engine, it was running fine then i uped the fuel abit with an adjustable regulator it was running fine for about 300miles then sudenly it started miss firing badly (3000 revs). So i changed the coil did nothing so i checked the injectors one was abit leen so i changed it did nothing (still running bad). So now iv changed the sparkplugs and fuel pump and iv put a normal regulator back on the engine and still runs like a bag of c**p. Today iv cleaned the crank sensor and unplunged the ecu and still it will not run at all the car will idle but as soon as i put it under load it splutters then back fires im at a loss with it if any one has any ideas Any please help its starting to make me go crazy.
