I just got through upgrading from the ESS VT1-535 to the new VT2-625 kit, so now I have more boost along with the addition of an air-to-water intercooler.
Looking at some past BT Tool data and comparing it with some data I captured today I noticed the intercooler has dropped the incoming air by about 40ºF in 4th gear at WOT over the VT1 setup!
Here a some photos I took during the installation. Enjoy!
