p1211 is injection pressure above/below desired.
means your hpop isnt keeping up with what the tune is calling for.
might need a new icp or ipr if they are worn out and not functioning correctly.
i had a bad ipr and when i swappped it i noticed a huge performance improvement.
if your setting an SES light thats probably due to overboost.
the chip should have a boost fooler built in so it wont defuel but will still set the SES light.
try unplugging the red line to the wastegate and capping it. also you can tighten the actual wastegate rod as well, but you have to remove the turbo to do that.
