Is your turbo in boost while cruising on the highway? Curious if your crusing on the highway @ 2100-2300rpm if your turbos are building boost or not? i am a tad concerned, i have a T4 76mm (82/87 with 1.10AR) being fed by a .030 over LQ4, entire build is targeting a reliable daily driver but now i am concerned my turbo may be a tad small (lots of fellas are running a T6 80mm etc) Currently building a base tune to get my truck up and running once its done but looking at the spark map got me thinking about it, because that would be a kick in the ***** to my fuel economy.

Won't be a problem, I'm 6L with 7875 in 4500 lb truck , boost is instant at WOT but you can easily drive all day and stay out of boost. If vehicle is lighter and more aerodynamic even less likely to see boost. If it were heavy with tall gearing and manual trans or locked up converter I'm sure you would get into boost quite easily but driving could be adjusted to stay out of boost if desired

Does the turbo spin freely? A turbo system is relatively simple, no leaks before and up to the turbo, no leaks from turbo to throttle body. You can remove and block off the WG or BOV if one is being used, but be careful, there's nothing to stop from over spinning the turbo.
