To much boost? Xtreme Street IDP

hey guys. i have an 03 Stroke with a 6.0 PSD. i have the following performance mods
SCT X3 with Xtreme Street ( i have more but this is the one i question)
Banks 4" Exhaust Straight piped
S&B CAI

my problem is that when im in my Extreme street tune and i am going up a grade with the torque converter locked in and i hit the skinny pedal the truck wont downshift and i will hit over 35 lbs of boost. my gauge only goes to 35 so i dont know exactly what it goes to. should the truck downshift if i nail the skinny pedal going up a grade or is this totally normal. from a digg i only hit around 34 lbs. if im on flatts and im doing about 70 and slam the skinny pedal to pass someone it wont downshift either. just builds a ton of boost and slowly excellerates. ive replaced the VGT selonoid and tore apart and cleaned the turbo. but it still does this. any ideas guys?

Re: To much boost? Xtreme Street IDP

My truck will downshift if I slam on the gas, but it feels faster when I ease into it and it stays locked, I think my 37s have something to do with it, I'd be careful pushin the turbo past 30.

ARP Studs and Egr Delete

And some other bling

Normal. It will hurt your turbo over time though. The bearings will go. My second one is going and I'm only at 40k miles.

Hit tow/haul mode and make it easier on your engine.

Re: To much boost? Xtreme Street IDP

Im gonna add to op and say its probably a normal thing. Well for me at least as well. No downshifting just insertion of more fuel and really smoky. Cant comment on boost # but shouldnt be too much off a problem as long as you dont do it all the time.
I thought about contacting idp about it but im not all that concerned.

Edit: Even when i hit tow/haul it wont affect the shifting. Neither will pushing the brake with tow or anything else if tried. Im guessing it takes 37s to change anything

Mine does the same thing running the Looney Tune. It pegs the needle at 35. What I do is just tap the Brake pedal while I'm still in the throttle and it will down shift.

You can tap the brake pedal to unlock the converter. Thats how it was when I ran that tune . The tune I run now will drop down and grab 4th with a locked T/C. Its nice.
