In another failed attempt to use an upgraded wastegate actuator, yet retain somewhat decent drivability, I made an interesting discovery.
I had been driving around with a setup that allowed lower than stock boost levels.. about 13psi max. Once I returned the boost control back to stock, I discovered I have about 17psi peak boost dropping to 14-15 b redline.
Now, I'm pretty sure that this is the computer re-learing how to control the boost, overcompensating if you will, for the limited boost I was allowing previously. My guess is this will eventually reduce back down to the normal boost curve.. however for the time-being, it's alot of fun:).
So what I think I will do is hook up a solenoid that blocks off the bleed from the factory boost control solenoid. For commuting back and forth to work, this, in theory would increase fuel economy due to slower spool up, then when the occasion arrises to unleash the full fury, the computer will compensate with this temporaty overboost condition.
I will try this and report my findings.
