Hello all,

Just installed my IC on my 603 and took it out for a quick spin just to make sure everything held together. It did so far, but I noticed a lower boost pressure on my gauge. The pressure builds up more slowly now and it tops out a couple of psi less than stock.

Now granted I just added 6 additional feet of plumbing underhood and I was expecting a slower boost spin-up, but is the lower presure limit due to the:
1. system capacity increase??
2. the cooling efficiency of the IC??
3. Leakage in the system??

I cannot hear any audible leaks while driving and none fealt at idle. I have not had much luck convincing my friends to help me take off the hood so they can lay prone on the engine bay while I make some full boost passes and then tell if there is a leak or not. Any takers on this list

Any help would be appreciated, expecially anyone who has done this conversion and noted the changes, experiences etc.

Thanks
