Hardcore Tapering...... (Update) Map Verified
28 PSI @ 4000 RPM - 20.5 @ 7000 RPM
Increase boost..... and
30 PSI @ 4000 RPM - 20.5 @ 7000 RPM
I am going to guess I have a major boost leak... Going to do some tests soon
.
I should be able to hold more than that..... since people like ElectricEvoIX spikes less and holds more
. Grr. Probably explains my low traps at the track

Im in your boat, higher elevation, does not matter what I spike to holds 19.7 at 7000, 18.5 at 7500, but nice 25 through the middle. But always seems to be the same at high rpm no matter what the peak boost. I travel between 3100-4200 feet. I have the forge as well. My friends stock IX with a flash hits 19 tapering to 16, he would taper to 14 before the flash. He was excited the other morning with the cold air held 17 psi.
