Do I reached out to Nero at Titan for the Downpipe and Protune. They took care of me and I got the products with a quick turn around for my track day. My shop got them put on with no problems plug and play. Drop the exhaust through on the down pipe. I ran map 4 which is pump gas and down pipe. I picked up over 2 seconds on my laps with work out tires and brakes. The air temps where over 88 but car ran like stock no issues at all. On the street the car feels like a beast from a dig it’s a big difference over stock. I want to through in some 100 octane and try some more maps.
