think my car might be smoking slightly

[grimm]

I noticed today that my car seemed to be smoking very very slightly after being fully warmed up. I just changed spark plugs recently to the one step colder NGK's. Could that be a cause. I know i need to look into it more as far as color and smell but I'm wondering if it's a smart idea to bring it to a subaru dealer to look it over. I have basically a stage 4 car. Aftermarket turbo, injectors, up and down pipe, headers, gutted cat, etc etc... Not sure how a dealer would deal with a car that is so modded. And can anyone mention a place somewhat local that might be able to help diagnose it, ie: percision tuning? or area 1320?

PE and Area1320 both are great shops. Either one would most likely be able to diagnose the issue.

Area1320 would be a good bet, they diagnosed my smoking issue (turbo is going on mine). But it does depend on where you live, they both have great reputations.

Where you located? Would Xotic Motorsports in Cochranville, PA be too far of a drive! Andy is the man when it comes to Subaru's!

I'm located in Bucks county. I'd like to keep it under an hour away, but that might not end up being an option.
