Lacking power, not hitting target boost?
Have a question for you guys, I have a 2010 5" dp back, running the H&S HD300 tune on Hot.
I have noticed that at WOT it seems to be lacking in power and will only build around 30psi of boost up until I get into 5th or the TC locks and it will peg to 40+ psi. Also I noticed that the smoke does not clean up like it use to, it use to smoke shortly until the boost caught up and then it would clean up, now it will leave a solid trail of smoke up until boost peaks (which now takes a long time).
Don't get me wrong it still has an amazing amount of power but it is down from where it use to be.
I pulled the EBP sensor and it looked pretty clean so I didn't bother pulling the tube. I pulled the MAP sensor (I think I checked the right one, there are two next to each other just behind the intake tube, I pulled the front one), it also looked fairly clean so threw it back on. Pulled the MAF, looked clean, threw it back in.
Should I go ahead and clean the MAF anyway? Could one of the sensors be bad and cause this? I have no CEL's and have never thrown one. I do not appear to be losing coolant either, it's been like this for a while.
Other then that it seems to run perfect.
