yes i deffinatly would park the car until your getting tuned. No use in spending hundreds to get your car towed to the dyno unless you have the spare cash or are a AAA member. I know i have neither, and as long as you take the proper percautions you'll be fine. My "incident was within the first 5 miles of leaving my house" i drove the other 145 miles on the highway flawless...and the car made 275whp on a totally stock LS motor. Compression and leakdown test today showed motor is still tip top.
