^ Understood. I do strongly believe in having a real time always functioning boost gauge. I prefer mechanical and have a VDO mechanical gauge. That's the single most important parameter to keep an eye on. It never hurts to monitor as much as possible, especially if you are going to be adding power mods.
You do need to datalog, IMHO, because stuff can happen in a fraction of a second that would not register on an analog gauge, but would show up on the log. One example was the gradual dropping in high pressure fuel rail pressure on my stock pump. Once it fell below 1400 psi under load, I knew I needed to upgrade the internals. What was shocking was my datalogging was showing that under max engine load at WOT down around 4,200 rpm in 4th gear, the pump pressure was dropping to 1100 psi for less than one second and then bouncing back. Any kind of real time monitoring would not have shown that dangerous downward blip, enough if it went unattended, could damage the engine. I do strongly recommend that you regularly datalog if you are going to mod this engine, and that besides boost, perhaps the most important engine operating parameter to look out for on this engine is the fuel rail pressure. The only way you can capture that, to my knowledge is through the OBD II port.
