Well, I currently have a S0 pcm map clamped, obiously to lean it out and hid the 20psi spike. Im getting a DSP so since im holding off on getting a 3bar map, would it be ok to Clamp the pcm at 17psi, and then use dsp to tune from there? The reason for this is that so when the pcm sees the 20psi spike it doesnt pull timing or freak out.
or will the 93 tune on dsp eliminate the issues above stock map levels?

Remove the Clamp. Its completely unneeded with the DSP. With the DSP 93tune, you will spike 20psi with no problem using the stock sensors. The PCM will NOT "pull timing or freak out".

guyss... 22psi hold on stock turbo? no porting no bigwheel not ext gate? you realize its not doing anything to help right? you realize its way past its efficiency range and you are just blowing hott air and the turbo is struggling?
16psi hold @ redline. thats it. stop wasting your time and breaking your parts.
No stock turbo will not hold 22psi at 6Krpm, but a breif spike is just fine if not desirable.
I've only see 1 log of anyone holding more than 16psi and it was 16.001, most guys are in the 12-15psi range regardless of which wga they're using and despite thier claim.
A TD04LR-15 will choke at right around 20-22psi,,,,,,So 22psi spkie is hardly "way past its efficiency range and you are just blowing hott air and the turbo is struggling"
I know the turbo wont hold anywhere near 20psi, but i want to spike somewhere around that. The meth/water injector helps alot with the hot air. Im also using a agp wastegate.
I just wanted to make sure it didnt start pulling timing, but i guess ill have to test it out and scan it
why is that? i dont get it. so basically me buying a 3bar map will be useless for running over 18 psi on a bigger turbo like the s256 and all you need is the tip sensor?

No,,,,,,,,,,
Stock turbo = stock sensors are fine over 20psi because it falls quick enough under the MAP's max.
Any other aftermarket turbo that can sustain boost over 19psi should use a 3bar MAP AND TIP.
