Ive seen some posts about Renntech offering a pulley/computer upgrade for ~5000, which is pretty ridiculous. The cars seem to be kind of similiar to the new 03 Cobra's in terms of engines (V8 With stock roots type blower) Those cars have been seeing incredible gains with a 80 dollar pulley, exhaust and a couple other little things. Have any companies spoken about making some products for the E55. I would think between a cat back exhaust, off road pipes instead of the cats, a smaller pulley and a ECU reprogram we could see upwards of ~600HP on these cars.
