Just replaced the spring in my Missing Link with one a little stiffer, hopefully it will seal off quicker now and prevent the map sensor from seeing any boost. I'll post back results after I clock out and go for a test drive :)

Absolutely Flawless!! Not one hesitation, I even pumped the gas pedal slightly around 0psi to really test the transition out and nothing!! I did that before changing the spring and the car felt like it was having a seizure lol. I'm so happy this worked!

Very nice. Congrats on fixing the problem. It sounds like it would make a nice little write-up for the wiki ;) I've never even looked at the ML enough to figure out how to take it apart LOL. I think someone should take some pics and show us :D
