I will be try to fix the flactuating maf reading my anchoring the whole intake assembly down. Right now it is held up by a flimsy L-shaped aluminum bracket. If that doesnt work, I will be trying MAP base tune. Anyone has any pointers regarding how to go about doing it? thx in advance!

 

I suggest you to do logging and try to plug in those logged timing numbers into the load sites correspond to the boost level. For example, using Map0 and do a 0psi boost (0 vacuum) run from 2000-redline. These timing number will be a good starting point for the -3 to 3 psi load sites. Repeat the process in 5psi, 10 psi, 15 psi and 20 psi, etc. It will take a long time and sometime it is very difficult to hold a steady boost with your gas pedal... now the boost control will be very useful.

It's is very brief, but I hope you get the idea.
