Hi guys I have a 1980 firebird with an LS1 swap. Doing a few winter upgrades to the engine and was wondering if there is a shop around northern IL, southern WI that are good with LS engines specifically. Looking for a dynotune and would like someone knowledgable about these engines. Thanks for the feedback!
