yep most likely, however we don't have all the facts in front of us so there is another possibility. the alternative answer would be that the previous intercooler was so inefficient that the tune it self was compromised and now that the temps are in the range of 20-30c they're able to add in more timing / fuel as there is now more denser air (more oxygen in the cooler air helps a bit with this too) = better combusion = cooler engine = safer engine = more power with same boost level. in my own example that i provided from my car, when switching from top mount to front mount i didnt make extra more power just from this as tune was already at limits and the power runs/tune was done at PBMS where they have proper top mount cooling setup, however my tune was setup to compensate for IAT so as i drove it hard during the hotter months, the ECU was pulling timing while driving to keep engine temps down hence i'd be driving around with fair bit less power on road than what i had on dyno which would have made that setup a bad choice for track use. not only is my IAT cooler but my coolant and oil temps have also been cooler since switching over which was weird because in theory this big object in front of radiator i would have thought would make it less efficient in that respect. goes without saying though that a good quality intercooler core definitely plays a big role in all this.

Heres some completed pics so you can figure out the rest. Pics with a Rev D manifold and different piping. I prefer this manifold as its like a Spec C Manifold where it doesnt have TGVs and the plenum is a better shape and size imo.
