Boost questions

So I moved my boost pickup to the AIH today. On the test drive I still only hit 26lbs max on my 140 tune. With that being said, I have read of people hitting 30 no problem and I'm just trying to figure out where it could be leaking from. I'm thinking of the boots, but I'm not sure.

Thanks!

Sounds about right to me. I've seen higher in mine but I adjusted wastegate 3 turns in.

Unplug the wastegate and give her a run. You sould be able to hit 30psi. If not, inspect for leaks.

I think strokin is telling you TO unplug your line. It will give you more boost. If yours in already unplugged and if your only getting 26 then you probably have a leaky boot. Rig up a boost leak detecter and go to town on it

I understand what Strokin is saying, and the line is unplugged. I'll be rigging up a boost leak detector today.

Thanks for the help!

That's what I was going to say, I think aslong as you're over 25 at some point on a hot tune you shouldn't have much to think about.
