Default I got the APR gauge in and electrical done, but there is a problem with the readings...

I went out did some WOT runs, I'm peaked at 13, maybe 14 psi. When I'm totally off the gas and in gear still it vaccuums at 16in. Hg. Do you think I'm not boosting to what a K05 chip does (I think it's 1.5 bar), or is there something wrong with the gauge etc. I rechecked the vac lines and there aren't any kinks.
Please help. Can I only check my boost with a VAG?


Oh yeah, on my last couple WOT runs, when shifting and letting the gas off, the gauge would flicker to 20psi, then go back down.

Default WOT in ... what gear?

I peak my boost readings in 4th, personally. But I've got a Neuspeed chip.

Default You should be in vaccum in gear when off the throttle, nothing irregular about that.

If you have a 1.5 bar chip you probably should be spiking to 22 psi or so, if you aren't check the bpv, and do some vag logs.

Default You should see ~19 in at idle and well over tha tif you lift throttle in gear. I would imagine with

a K04 you'd see above 14psi hold let alone peak. I suspect a boost/vac leak.
