The front and rear O2s are different, had to get new ones anyway. I read a thread on here 10 years ago claiming HP increase from descreening/polishing maf, so that was trash too. Man i hear ya, wish i took it home and installed the sensors myself. What killed my bill was the 6hrs spent figuring out the sensors were not reading correctly.

Talk to Tooley about it.

Comp changed the engineering behind these cams in 2015. You shouldn't be having the issues.

And sometimes, it's worth it to just pay someone else to clean up the car. I've chased my tail a few times and would rather just pay a shop sometimes to do. But the O2s are not a huge issue once you knew they were a problem.

I don't know Adam, but his facebook page looks like he does a lot of metal fab work. I may have to give him a call. He uses David's Machine shop in Mobile. And that's a good shop.

I wanted to add to this thread to make people aware that the Comp Cams cam whine issue appears to be far from resolved.

In March 2017 I purchased a brand new FTI Streetsweeper HT cam directly from FTI which is ground on Comp Cams lobes. I received the cam roughly 3 weeks after I purchased it which tells me that the cam was more than likely made to order from Comp in the March-April 2017 timeframe. I finally got around to installing the cam last weekend and I unfortunately have the very distinct and dreaded cam whine. It sounds 100% identical to the videos of verified cam whine posted in this thread and others. I am experiencing the whine with both belts disconnected thus removing the belts and accessories, etc from the equation. The car did not exhibit this whine at all whatsoever prior to the cam change. I was under the assumption that Comp corrected the issue based upon various posts indicating such but that is simply not the case. I am absolutely livid as cam swaps on a C5 are a real PITA and the whine is very noticeable and annoying. I will be contacting FTI and Comp Cams this week and I will demand that this be made right. Here's your warning, I'd personally avoid a Comp cam like the plague. It's a shame as I've had such great luck with their cams in the past.

i just installed a BTR stage 4 in my car this summer. I must of got one of the good ones because it has zero whine. I didnt get this lucky in 2013 with another comp cam.

Comp is just not getting it lately; cam whine, bad trunnion kits, and further back, bad valve springs... QC is lacking...

My custom grind I just purchased in January of this year whines like a MF in my grand sport. Same as my truck did, and my camaro before that. I'm done with comp stuff.

You are part of a growing "family". Unfortunately Comp has enough mainstream customers they will likely never get the message, or just not give a rip....

CAMMOTION PERF

Cam Motion is here for you guys. Remember, ever single one of our camshafts is CNC polished after it is CNC ground. We make sure your new Cam Motion camshaft will operate smooth and quiet.

^^^^These guys have the goods! And they're good!

I’ll agree: CamMotion is the way to go. When my comp grind whined, Comp pretty much told me to contact the vendor I used. My vendor was willing to help: but couldn’t guarantee me much.

Cam Motion’s team helped me out when I was in the bind. It didn’t save me the extra labor and time, but at least they went the extra mile when they didn’t even need to.

If they help non-customers like that, I can’t imagine how well they treat their actual customers! If there’s another cam swap, I’m buying the CamMotion grind!

I just came across this thread. I have a recently purchased Comp cam. Is there any way to indentify visually if it will have this issue ?
