Really good info here! I think at the end of the day, there are some tweaks to the tune that need to be made to optimize use of the intercooler?
I think it would also depend on how your tuner is tuning right? I know I loaded my LMS tune and it worked but according to Matt it wasn't optimized. I know that my WGDC on the LMS before and after was different.
Here is a snippet of load vs wgdc between the E30 LMS tune I am running before and after IC install. Same temps outside.. Before I would peak at 72% and the curve was a bit flatter. After I would peak over 80% and the curve is not as flat.. same load same weather.
