Slipping 8 speed automatic I have not remedied the problem. Through a series of events I have been unable to return the car to a dealer. I had some help from a contact at the GM Tech. Center in Michigan and he put me in touch with a contact at GM Headquarters in Detroit. He opened a case...

Yeah, and mine is a year old, still no fix! I agree, this should have already been addressed. I know I'm not the only one as I have asked others and they too have experience this. Jim

My early build 2015 Z51 automatic exhibits a "slipping condition" upon drive away when sitting over night. GM says they are aware of the condition and are in the process of readying a fix. Seems the fluid drains from the TC when sitting and must pump up before drive-away. I performed a test...

C7 Roof noise I have spoken to the Corvette Brand Quality Manager and there is a fix on the way. The new parts are now being installed in 2016 Vettes but they needed to build up the inventory.

Thanks, I have tried that to no avail. Definitely coming from within the top. I will post once I have a dealer evaluate. This may take awhile as I will not be able to do it for a month or so.

My 2015 Z51 Coupe emits a "popping and cracking" sound from overhead when the roof is installed. When I remove it the noise goes away. I note that earlier C6 owners had this problem and GM issued a fix bulletin and replaced the roof if the fix didn't work. Anyone else experience this? I have...

My 2015 coupe is making a popping and cracking sound overhead when the roof is installed. It seems to get worse as the ambient temp. raises. I have removed the roof and it goes away. I have used silicone grease to lube all obvious areas to no avail. Anyone else experiencing this? Since my...

Hib is right I recently purchased a 2015 Z51 Coupe. Took delivery in Michigan and drove it down to Florida. When the weather is below the specified range for "summer only" tires, they chatter even worse. As sticky as these tires are in warm conditions, they are like hockey pucks when cold...

I went with a dyno tune Hib, I ended up going with a custom dyno tune by an engine builder and tuner in "Nunica, MI." by the name of Baker Engineering. A young fellow by the name of TJ did the tune and I couldn't be happier. Turns out the engine was lean off idle to wide open where...

The latest on my tuning debacle

No new codes: Hib, I took it out today and drove about 25 miles. Ran it up to 6000 rpm in second and third, nothing happened and it seems strong. So, did my MAF cleaning work? I don't know yet but if the check engine light doesn't come back next week when I will be driving it more, we may...

THANKS, Yeah, I caught this, in fact the sales guy at DiabloSport dissuaded me from buying a Predator and turned me on to the "InTune" and Diablew, who is one of their preferred vendors. Turns out, I won't be buying one after all, at least not now. Regards

I saw the check engine light on the way home from running an errand, pulled in the drive and shut it off. Latter, I pulled the codes and found the two referenced earlier P0101 VAF CKT Range/Perf and P0101 MAF or VAF Range/Perf. Latter I pulled it in the garage and shut it down. Ran to the...

Cleaned the maf sensor Thanks again Hib. I just cleaned the MAF sensor with MAF cleaner and checked the codes again. Now, bear in mind that I had shut it off and restarted once since my last post on the codes indicated. Once I cleaned and reinstalled the MAF I plugged in the OBD2 Scanner and...

Thanks, I too thought of this and will try. VaraRam swears that the oil on the Green Filters won't do this but who knows. I didn't look to be over oiled but this is the route we will take first. After about a half dozen pulls on the dyno it's entirely possible.

Yeah, I took a risk and perhaps I will pay. Hope not though as I believe he really is going to stick with it until we get it right. Stay tuned. Good information. Thanks

Hold the presses!

More on z06 tuning issues Ok Hib, and others who responded to my "DiabloSport" post last week. I found a fellow in Traverse City, MI. who runs an auto fabrication business specializing primarily in Acura NSX's. He recently purchased a Mustang Dyno and is in the process of building a NSX race...
