Too much boost for a 5.3L right?
Lag depends on cam, tune, convertor etc. Lots of variable. The small exhaust housing will lesson any lag. But lag is a form a traction controll. lol too much boost not sure what you mean. You could run 5lbs if you want to. Be a waste but could be done.

Housing can be swapped out and or go to 76MM turbos if that is needed. HP cores I beleive are 4.5 x 4.5 x 10 each been a while since I messed with them.
