awesome man. welcome!
What brand leds did you use in your car? All mine are sylvania zevo except for reverse lights. My reverse lights are phillips. I love the additional light output of the reverse led lights! Wish I would have had them when delivering pizza. Mine is an ls so no turbo :/. My gas mileage was bad when delivering pizzas. I had many vets to compete with so I drove it like a race car.Welcome to the forum!
I also added an amp/subs to my car, and swapped out all bulbs besides headlights with LEDs! And I used to deliver pizza with my Cruze too. The only thing I didn't like about it as a delivery vehicle was the inability to separate the key from the key fob. When I delivered with my Cobalt I could leave the key in and the car running but take the key fob with me and lock the doors. That way I could leave the AC/heat running, save wear and tear on the starter, keep the headlights on in dark situations, and warm up my car when it was snowy/icy without worrying about someone stealing stuff out of my car or stealing the car itself.
I felt bad for driving my Cruze hard, then shutting off the engine. Turbo vehicles prefer a little cool down time before shut-down to avoid boiling the oil in the hot turbo. Luckily the Cruze has a system that pumps oil even after you shut the car off, I could often hear a whining noise coming from the engine bay after getting out. Besides that, averaging 25-32 in harsh stop-go city conditions was pretty nice! Now I'm a Quality Engineer and use my Cruze for commuting only.
