I have reached out to Dennis Kirban and He did not know of anyone to support me in this area.
A number of years ago I was able to find a mechanic in Toronto, Ken Seggie, who did some work for me.
New turbo upgrade, new fuel injector upgrade, intercooler outlet mod, fuel pump upgrade and fuel pressure regulator.
I think that was all but I cannot find the receipts.
Before all that a 3" exhaust from cat back was installed.
