Hey guys,
A little help needed here. I have an 07 vert that has the front end clunking (very bad) and the rear end whine when making slow turns. I see that many of you have had these problems as well. I have a C&L CAI and a BrenSpeed tune. My question is: Do I need to re-install the factory air and reflash to stock in order to get warranty work done? Also, after reading all of the posts here I figured this would be a well known problem that dealers would know about. I called two service advisors at dealerships here in Houston and they had no idea what I was talking about. Same with ya'll? Thanks in advance.

 

take the c&L off, ref flash and take it back. The TSB is found here somewhere. I know i printed a copy and took mine in with the Fuel tank TSB to my service manager and have mine there now.
Reflash just in case of them hooking up the and updating and messing things up. Cheap insurance.
