Def something wrong, either bad gauge or vaccum line is kinked or has a hole in it. I assume the car is running good/ making boost

Dont those things have a break in tune that keeps the boost low until 3-4k miles?

no hell no. Its like 50 miles or a certain amount of key on/off counts. Make sure your buddy is going WOT. If hes not, he will not be seeing any most anyway because of the boost bypass. One of these threads start atleast once a month with some new owner getting a GT500 and complaining he cant get any boost. Then after a few posts and days, we find out the OP wasnt going WOT!!

I was reading some of the remarks and i dont know what op, or wot means. I know im new to this just trying to figure things out. What is a boost bypass for? All responses are appreciated.

Thanks

Short versions:

By the way, WOT=Wide Open Throttle.

There is a config in the factory tune that does, in fact, count miles and/or key cycles and it limits your boost to a percentage of the total possible. It does not limit it to "x" p.s.i of boost. This was designed so that boneheads in transit and lot boys wouldn't beat the snot out of them.

There is no vacuum leak because it's not a mechanical boost gauge. The gauge is electronic and it works by calculating various factors and coming up with "inferred" boost.

For the OP, tell your buddy to kick it in the ass....but not now, he'll end up in the ditch on those tires in the cold.
