Default Wastegate Arm

Hey. I tried turning the WG arm today, and I turned it maybe 6 full turns, and it now will boost 15-15.5psi now. Also, in 5th, when it spools it'll hit around 15, then drop off real quick down to like 12-13psi. Is this normal?
I'm afraid to crank it anymore in fear of breaking something.

Forgot to mention I've got a Stage 2 ECU reflash It's tuned to 18psi. Target boost is 17.2psi.

What/who's map exactly are you running?It's normal for the boost to taper down towards redline around 5500-6K.Is there still threads left on the wastegate arm?Just trying to see how far you have adjusted it.

The free XPT map. There were a few threads left on the arm, but I put it back to stock now though.

How do I detect a boost leak while the car is standing still? I hear a whistle at around 10psi and goes away at 12psi.

There are no free XPT maps. There are stage two base maps.

I know the XPT are all paid, I just couldn't think of the name of the free ones, mostly b/c there isn't really a name

Make a boost leak detector and pressurize the system with an air compressor.

You can do it with a bicycle pump if you are creative.
I found the stage 2 base map from XPT the boost did fall off alot at high RPM and tended to wander a bit.

I should be wrapping up the first version of my 93 octane map this weekend. I don't know if I am going to post it for open DL, but I may email to certain folks if they want something to compare or test with.

What's the difference in your map vs the XPT map?

well, your boost will taper down no matter what, especially with that snail, the td04 lol, u won't be able to hold much boost with that thing.
the gmboost version is much better, helps to hold a bit more than the stock

I actually just finished the plug/play wiring for the GM and stock wiring earlier. I'm ordering some tmic gaskets to help find the boost leak before I really up the boost to target 17psi.
