If anyone knows who this is please reply to this tread. I have a question about a ported MAF affecting an A4. there used to be a website where he talked about this issue and had a additive to fix the problem. http://xs-fx.com/raughammer, here is the website that doesn't work anymore.

That guy is running some awesome times.

 

I haven't seen him post on here in a LONG time. You might try www.ls1tech.com, or just ask the question here...

 

John Campbell can be found on LS1Tech.com. I can't recall the additive you are referring to, but I assume its to help eliminate the chatter or stutter you have with a TC and a ported maf. Usually a problem with larger stall convertors.
