cammed 09 c6 ls3 corvette
I have an 09 c6 ls3 vette. I just got it back in Feb 2014. I had a cam installed and torque converter along with a dyno tune. When I got the car back it ran great just had to get used to the lope in the aftermarket cam. A week ago I had billy boat prt exhaust installed along with a vararam intake. Once I had the intake put on I noticed my car started to run different. When I pressed the gas the car would hesitate as if I wanted to cut off. So the guy at the shop where they installed my air intake and exhaust said I needed to have it re tuned on the dyno. I did it, the dyno guy said he lowered my idle adjustment from 1000 rpm to 800rpm as well as changed my fuel adjustment. To make a long story short now my check engine light came on two days later after I left the shop and the car runs a little sluggish. The car only have 22k miles on it. What should I do to fix this problem what could have caused it. Is something that could b major or a minor issue. Can someone help me. I am new to the Corvette world

It could be a lean code. Was the tune adjustment done by the same person who originally tuned it after the cam install? Make sure to go over all the connections on the vararam and make sure there's nothing loose.

What does code P0716 mean
Thanks. I took the car to auto zone and had the code read. It could be a number of things vacuum leak, o2 sensor, etc. I took it back to the place that tuned it and they scanned the code and he said it was the o2 sensor. The one before the converter. He cleared the code as I was on the road about 6 miles away to purchase the o2 sensor. While stopped at the light the car did a hard jerk motion forward and another service light came on. As I took off the car stayed in one gear. I eventually pulled over cut the car off and restarted it. Once I drove off the car began to shift normal. I changed the o2 sensor and cleared the code. This code read P0716 saying Turbin input shaft speed sensor circuit.

No two different tune places. Speedinc in Schaumburg did the original tune and Straightline in Joliet did the air intake and re dyno tune. But I will double check the connections
