Jerky on acceleration
Hi guys, recently had the ecu go on my classic, replaced it but it seems to have lost power, it does have a unichip piggyback on it. Anyway when i put my foot down it accelerates slower and in every gear it loses all power just for a split second and then is back on. When i hit boost its fine and doesnt do it but it doesnt feel like its hitting as much boost as it should even tho my gauge is saying it is. It has even kangaroo hopped a couple of times when ive accelerated. Do i need to get it remapped again since i replaced the ecu or has anyone got any suggestions that i can try?
Thanks
Thanks

does your engine check light work? i would connect the test wires and see if its stored any faults, i had the same problem, it flashed out as being the knock sensor, i removed and cleaned it and reset the ECU and as yet its fine, drives smooth with full power again.
hope this helps.
