well it completly stops momentem and happens about every 500rpm over 5500or 6000rpm, and since I cant find any info to help me tune the avc-r its boosting to 14psi. I have it set in A basic tune with .60 bar and 30%duty
yesterday i had it pushing 12.3 psi but then when i got in it today and smacked it went back to 14psi WTF!!!!!!!
Im guessing the hesitation is the igniton from pushing to much boost?? but I dont know

 

What are your mods? "If" you are running stock ECU then the hesitation is fuel cut but I hope you are not running anyhting above stock boost levels without an aftermarket ECU.
