Hey is anyone experienced the codes mentioned. Running a beta tune and throw a high rail pressure code on a pretty regular basis. On the dyno I had a overboost code as well.
A guy would wonder if the codes have a negative impact on making power.

I guess I can buy a boost fooler, but I'm stumped on the high rail pressure.

Cheers

I was throwing the high rp code too friday night when I was at the drag strip with the new beta smarty that bob sent me. On mine it was spiked after I left off though which it should somewhat just didn't throw a code on the wild smarty.

 

Yep my truck has been throwing a rp code to with the beta 4.4.
