Ever ridden in the back of a Jeep? That's about what the T5 cars ride like if you bump up tire pressures like that.

A learning experience is one of those things that says, "You know that thing you just did? Don't do that."

Eeked out one more mpg (up to 22) on this last tank taking it a bit easier on the boost. I can't help but dig into it every now and then. I think I'm going to add a boost gauge just so I can have more of a visual on what the turbos doing. Any thoughts or advice on putting one in?

He didn't say he was worried about ride just wanted better fuel economy! Just giving other options!


No a/c, no lights, minimize load on engine! Tune up and see where your at?!?
