cant rev with pfc, drops rpm to idle
 

Topic says the problem. My car works fine with original ecu, but with pfc it idles good and everything but wen i try to rev engine it revs about 1 sec and then flats to idle. What can be the problem. it seem like it cuts fuel.. also i noticed heat warning light is on all the times. My car is -93 fd with nonseq, intercooler, intake, dp, catback, rad upgraded.. Also i checked sensors and vta-1 was highlighted and reading was 4.86, my car water temp was 82 when i started installing it cos i was just driving with original ecu. The water temp correction highest point was 80 but i didnt dare to touch it cos i dont have manual for pfc and dont know exactly what it does. And sorry for bad english. Its not my native language
