Great Gains

Maintenance and modifications go hand and hand when tuning these cars. People often eye roll and question us when we mention a few items that need to be addressed as miles get up there and years go by. While there are many tuners that don’t require maintenance items before tuning, we will pass on the job if we can’t do it the right way. This ensures a seamless tuning process and a healthy car for years to come. When the car leaves you with a dead cylinder, you’ll wish you did the few hundred in maintenance items.

Dave’s car was in for some light maintenance, exhaust, intake and intercooler work along with some cool live AFR logging utilizing @cobbtuning CCF features. Before / after graph pictured prior to exhaust, inlet and intercooler – big gains everywhere!
