There's a lot left on the table with the combination you have, and the vast majority of it is going to be in getting the fuel and timing curves optimized. Like hondaguy72, I immediately looked at the cam timing as a standout with the existing cams that you have. The thought is getting a set of adjustable cam sprockets and doing loops on the intake and exhaust cams and seeing how much of a difference it would make in terms of boosting the torque lower in the powerband. Elsewise, I would get the stock cams and reinstall them. You are not going to miss the power, and if anything the car will run stronger because you brought back some of the missing low end torque.
I am passing on what this guy did with his DSM Laser.
