Default Harmonic balancer needs replacing. Optioning

Well I will give a little background. 2006 coupe with boltons. Headers, PFast VRcia and tune. 129k miles by me. HB is started to do the wobble.
Q. What UD pulley is best other than OEM which I have not ruled out.
Q. Mechanic racer of mine likes SLP, 10% so no issues with electrical, do you agree.


Thanks

What % is it and what performance if any did you notice. I hear mostly sotp only. Is the throttle lighter?

It's not an underdrive. The quality is superior to the OEM HB, that became rusty and (hence?) wobbled. I bought my ATI from Katech.

There appears to be some surface "blems" that someone has found for almost 1/2 price re ATI. Do a search on C6 gen and tech for the thread re ATI. They're not underdrive but the difference in HP is not enough to count. From what I've read you won't go wrong with either SLP or ATI but it sounds like the latter is still the fave.

That would be me . Search ATI Blem on eBay and you'll see what ATI is currently listing as blemished balancers. They put new batches up every few weeks. Mine is not underdrive, but they did have underdrive out there when I got mine. Best deal going. There was nothing wrong with balancer aside from a few scratches on it, which you'll never see once installed.
