    Boosted Srt8 PR Wont Read Over .99?????

    like the Title says I have a boosted SRT8 Challenger on the dyno and the first pull I made it made 10psi according to my map sensor and my sensor hooked to my dyno but my Pressure Ratio that im monitoring will go to .99 and stop and just flat line. this makes about the 50th boosted SRT that I have done and this is the first time ever seeing it stop at .99 does anyone have any idea why it will not read like normal? I have the PR limit to 3.0 and my map sensor is scaled correctly. im stumped at this point and helpfully its just something stupid im looking over.
