That's going to be a lot of coin the 128 box retails for about 2k; harness and sensors will probably be another 2k. Not to mention if your going full PI; you still need to upgrade the entire fuel system which is probably 2.5k on parts alone. This is just a more viable option than meth in my opinion. As with an extra 2200cc injector you can run more e85 and not have to worry about a method pump failure;etc.
