When upgrading stock Turbo downpipes, how do we calculate what is the optimum size for best flow while still keeping the the Velocity high ? I have upgraded my Dp from a 42mm to a 63mm, and even after a Tune the car feels laggy at low rpms. It only comes alive above 3k Rpm. If you calculate the area of the Upgraded DP, it works out to 2.25x the size of the Stock DP. On stock cars with small turbos, what would be the best upgrade in Size for both Performance and maintaining the Daily driver characteristics ?

if there is an internal oil limiter in the turbo, is an oil limiter also needed in the supply line???
