The problem I have had with similar systems that I've developed, and even the Mann Pro- Vent has been proper balance of long term fuel trim. How have you balanced this? I saw engines always tend to go near full rich on deceleration when using a system like this.

I have also found that the volume of the canister is directly related to engine output, and displacement. The 2.5 and 2.7 engines needed a completely different volume compared to most of the engines that were larger. When I got up to my 3.8L engine, no room was left in the engine bay for the canister, and a remote reservoir had to be used in addition.

I can give you some comparative info if you can send me a test unit.
