Besides the powder coat on the CAT vs the bare Slee, the only real difference since they both relocate the ECU, is that the CAT is under the ECU while the Slee mounts the compressor on top of the ECU. The twin brushless is so powerful that it inflates four 35"s from 15psi to 36psi in about 3-4 minutes so although it gets hot, it's only for a short amount of time and there's no risk in "cooking" the ECU.Since you have the CAtuned kit, would you happen to have any opinions on the Slee setup vs CAtuned? Trying to decide between the two.
