Hey CDC. I have been on this forum for years. The fact is the aftermarket support for our car is frustratingly limited. I have a cold air intake, bigger TB, injectors, ecu tune, exhaust, plenum spacers there are a few high ticket items left for me to buy but the reward is not worth the cost. Look into the engine swap. I have been weighing out which direction I want to go with the car for a while now. Here is my main issue with everything being MB based and a limited aftermarket anything produced is extremlely expensive. On top of that the computer is a pain in the *** to tune. I am currently taking night classes for welding so after I become confident enough I am just going to yank everything out and do an LS/T56 swap. Why because 'murica! I lose my my abs/bas and TC but wide tires big brakes and common sense will get me through. I love the crossfire but fact is its just slow. The cold hard facts is right now I cant afford a vette so I will make the best with what I have with a car I love.
