No chip or anything its all stock 93 computer stuff. Think the pro-m 83 can only go to 440rwhp? I would think it could do more than that. Half the people I talk to say pump is the problem and the other half say injectors are to small. Going down the road and getting on it I don't see the FP drop any. I know its one of the two just don't want to buy both if only one is the problem.
