me and viet took the car for a 15psi tuning run and got it running pretty good. its decently quick now. tuning is not a quick process though especially since i had to make a whole new map. we spent 2 or 3 hours and a trip to bradenton just to get a rough tune. it still needs some tweaking. its getting easier though as i learn how to make the right changes but 15 is fun. I noticed the cars going by alot faster on my way home from work
