It has been said that the boost screw is cocaine encrusted.
Everything is fine, well, just a little more boost, a little more hp, good, now just a little more, until everything explodes.
Pleased to hear of your successes.
The more horsepower you produce the less time you are on the throttle. However, more power means more heat. You can tame a bit of heat by running on the rich side.
Lean on full boost is a nightmare.

Yeah she is generally still running pretty rich across the board. Been leaning out the bottom and mid points only off boost to get back the snappyness. These are the only areas I'll target 14.3 afr so I can use the close loop and smart tune function of the SESTP.

What afr and timing have you been running for your safe tune (under boost)? Getting about 6psi right?

Till about 7psi pulling .75 degree for each psi of boost. Over that 1 degree. On boost targeting 12.5 afr, but running a little richer generally

Plumbed in a Boost Controller Tee, now running about 12psi. Dam, she flys! Pretty sure I had her light up the rear wheel coming on to boost! Very happy with the end result!
