Lag is based off of size of turbo, distance from engine, heat and velocity, exhaust pipe size. There is a balance between them all that must be found to minimize it. Oh and not to mention turbo inner works such as old school heavy weight turbines/ ball bearings vs. ceramic ball bearings and light weight turbine wheels.
I will retain my stock compression ratio so torque should remain the same until boost kicks in. This is what I suspect as of right now. I'm planning on about 5 lbs of boost. Deciding on adding additional injectors for a stand alone controller, factory ECM will be untouched. So idle and power remains the same until boost is detected by 2 bar MAP sensor. So many thoughts on this.
Some times you have to think out of the box at a distance of 50 feet, and not letting someone tell you it can't be done.

Very nice, Tony!
