So after around 3 years of dealing with ERPM and searching and never really finding a complete answer and thinking the problem was fixed when it was just intermittent, I came across a Thread the other day from Wildman stating that EFI live has a boost error table that HP Tuners does not have to offset the boost error "or the difference in desired boost and actual boost". What they were saying the issue is, is the MAF and the desired boost tables run hand in hand and if the one is too much different than the other it will cause the ERPM, so in order for us, "HP TUNERS" guys to fix the issue you can go in and,
1-Change the desired boost tables to what you are actually showing on a boost gauge or reading during a scan, or in my case it was my race tune and I knew I was not achieving my desired boost levels. "this is how I fixed mine initially"
2-Changed my Boost Max table, in my case I had mine at 400kpa as I wanted as much boost as I could get "NOT RECOMENDED" I then changed it to 320kpa instead of changing all of my desired boost tables as it will not desire over 320kpa now and this is a much faster way of doing it.
3-Rescaling the MAF to fool it into thinking it was getting as much air as you was desiring in your desired boost tables, "I have not tried this option as I am not terribly familiar with rescaling or changing my MAF and I was able to fix the problem with the other 2 options.
Hopefully this will help someone, and there could possibly be a thread on this already but whenever I searched I couldn't find anything!
Happy Tuning and Happy Holidays
