Hi guys and new to all this turbo stuff so bear with me. I have been doing alot of reading and know that once turboing my 420a I would have issues with fuel delivery and that you have options like ms, some other tuning, the fmu/missing link/or fcd. Now I live in PA and have emissions and inspection and found that as long as CEL isn't on it will pass emissions but would adjusting the ratios (or whatever they are called) within the ecu or buying a new one that is programmed with all the specs you will need be considered tampering? I just don't want to put out alot of money for something that will not be useful in regards to emissions/inspection pass/fail.
