I know this section says Duramax but was wondering what/who the most knowledgable 8.1L tuner is? I am looking for someone is done these motors and knows what output numbers are after the tune. In market to get one in January (begining). I live in Columbus, Ohio, but will be in eastern Tennesee next week if anyone tunes there thats good. Thanks for any info.

I believe I have spoke with Nick and from what I understood he has not tuned an 8.1 yet. VERY nice guy and I wished I lived closer to him so I could be his guinea (spelling?) pig for tuning them. Its hard to find anything for an 8.1 it seems, now so since they dont even make them anymore :( Was wondering if anyone has actually tuned an 8.1 on here. Wonder what kinda numbers I would get. ???

Chris,

I got your PM, and I'll give you a call today. I have tuned two 8.1s recently, and am hoping to work further with a member on the gas board here to make it perfect. It's only been a couple weeks, so results are preliminary but things are looking good.

Hopefully they can chime in here with their results or updates.

Have you dynoed your tune for the 8.1s by chance?

Wester's ..........can get ya' 70 h.p. or anything in between, according to which octane fuel you want to run. I have dyno tested a 6-liter gasser that he advertised at 50 h.p. to the REAR wheels and it did EXACTLY that!! So,I feel like you would see the 70 r.w.h.p. if tested. I can't think of his web-site, but you can p.m.me and I'll hook you up with him if you like.;) Good luck, Ed.
