my car has started running very weird now, it doesnt seem to hold idle at low rpms anymore, it doesnt run strong....its quite lazy.... all this 2 months after it was dyno'd and tuned to perfection.

I will attach a composite log.

 

Your composite log appears to show normal crank and cam trigger operation. Unfortunately, composite logs say nothing about the tune or about the operation of anything other than the camshaft or crankshaft position sensors. A regular data log of the engine idling, accompanied by an MSQ file, would be more appropriate files to help people who want to help solve this problem.

 

Have you checked all the simple stuff? AFR? Spark plugs? Compression check? It might be worth pulling the valve cover to see if a cam gear jumped a tooth.
