Yur 3 paragraphs still don't specify yur source or any hardcore data (my original question). but whatever.Has anyone complained about lag with an upgraded intercooler? While the abscence of complaints doesn’t mean there isn’t any lag at all, it’s a pretty good indicator that it isn’t noticeable.
As I understand, the 1.5T tuning logic is a torque-based MAP configuration. In this logic the throttle blade, MAP and boost controller are all used in tandem (with checks to IAT aka post intercooler temps) to create torque. In other words, the ECU targets torque, not boost - this type of tuning logic is a lot more consistent. So, to add to that consistency you ensure that post intercooler temps are consistent.
This all relates to the “fill/lag” time by virtue of the tuning logic. Believe it or not, the ECU is bleeding off boost to keep the turbo from spooling too quickly - see Ktuner ramping options. The ECU is expecting X torque via inputs in X conditions and if the intercooler is larger and fill time is increased, the ECU will either slightly close the throttle or allow a little more boost to achieve X torque under X conditions.
