Couldn't agree more with this statement. Seen too many so called tuners do a few WOT pulls, adjust the MAF table, take out some torque management, and charge the customer $500+.
A proper tune should include both dyno and street tuning. My biggest beef with most tuners is they disable the speed density portion of the tune and make it MAF only because they don't want spend the time to tune the SD side.
I have to ask the OP how you know you have a failed high side fuel pump. Did your tuner tell you that? That could be a lot of your problem.
