Still Boost Problem, Possible reflash needed?

I went to the hardware store today and built one of those DIY boost leak finders, set the AC at 20 no leak bumped it up to 30 still no leak. i got some soap out figuring i woudl be able to see bubbles and still nothing, not around the spider, not around the IC boots nothing. No soot on the uppipes. i have absolutly no idea what my issue is.

Do you guys think that i could need a reflash on my DP tunner, I got it a month or two ago when i sold my other truck, i just am curious, i have the loop idle on thre which is suposto make smoke and it dosent do a think....

The lope smoke idle works differently on different trucks. ZX250 told me that in order for his to lope he has to start his truck in that tune (IIRC)

What is your boost issue?

As for the lope and smoke tunes, they don't work well on my truck either but then again I don't care because I have no use for them. I think I remember him saying those tunes work better on trucks with bigger sticks and I also have to start it in that tune for it to work. Otherwise it sounds like the drive thru tune, which again I have no use for so it's hard for me to remember exactly.

What is your fuel pressure during WOT on that 120 tune?
If it is low, you won't be getting enough fuel to drive that turbo.

Gotcha, Dan has a good idea on something to check. And forgive me if you've explained before, but have you done anything to the wastegate actuator? I had to tighten mine up and disco the red line to it.
If your up pipes are leaking that will cause this also, I know you said they are fine but they are very hard to inspect.

Edit - ahhh never mind I think I see you have a waste gate delete done.
