Show me a 3.2L that they used the factory ECU WITHOUT a piggyback, FMU or RRFPR and I'll eat my underwear and post the video on you-tube! That's what I'm getting across. This isn't about doing it but how it's being done. Tune or no tune, the stock computer CAN NOT read MAP and therefore cannot read boost. Something else has to be part of the equation to make it all work. Don't get me wrong, the guys at LET are great and know their stuff but they aren't just doing a tune and bolting up turbo's or SC's. If they were, we wouldn't have a thousand threads titled "can I add a supercharger/turbo to my car", we would have a thousand threads titled "dude, I just added a supercharger/turbo to my car and holy jeebus"
