Who did your tuning? Familar with Doug Rippie performance in Waverly MN?



I am thinking about a dyno tune on this after the stall, is there much to be gained or would sticking with Justin from BBP be fine via the autocal. What do you guys think? What would you do? Prices is looking like $400-$650 and the higher end is a dyno tune, the lower price range being for a wideband street tune (with HPT i believe) which seems not much better than the autocal route.

I really think that 600+ could be better spent elsewhere unless you had a lot more mods or weren't particularly pleased with the tune for some reason.

I guess i am considering it mostly because my truck is still baseline tuned so it runs like ***! Waiting on my retune from BBP and its killing me each day as my new truck is sitting in the driveway in a less than reliable driving condition cause the tune needs so much work. Not knocking BBP at all, it just sucks waiting on the retune. Considering the Dyno tune simply because i could have it dialed in real well and hopefully make a few runs for some HP/TQ #s.

Just get the dyno tune.... All I'll say is been there done that. In the long run you'll be happier! 1-2 weeks wait times is for the "Hypertech" crowd.

Got em off a guy on eBay. In the process of ordering some black stainless "lsx 376" emblems to put on the door where the sierra emblems are. I'm thinking I'm going to have to just spend the money and get the dyno tune. The delay waiting on tunes and the fact that it would be better dialed in is appealing. Live and learn, gotta pay to play.
