SouthPawCO Posted September 14, 2016 Share Posted September 14, 2016 That is a pretty significant increase with just bolt on's, impressive. Quote Link to comment Share on other sites More sharing options...
NWarrenZ71 Posted September 26, 2016 Share Posted September 26, 2016 I wish there was someone near St. Louis that did dyno tuning like this. I'd love to tune my truck but don't want it done remotely based off of what my parameters "should" be running at.

Crobinson16 Posted May 23, 2017 Share Posted May 23, 2017 (edited) What made you decide to go with 1 3/4 vs 1 7/8 headers. Thanks for posting the dyno numbers, wish I could see a comparison to a set of 1 7/8 I'm trying to decide what to go with for my other wise stock 2011 6.2 I am running a black bear tune Edited May 23, 2017 by Crobinson16 Quote Link to comment Share on other sites More sharing options...

Thanks for posting the dyno numbers, wish I could see a comparison to a set of 1 7/8 I'm trying to decide what to go with for my other wise stock 2011 6.2 I am running a black bear tune There isn't much difference with the two, the 1 3/4 will give a little bit more low/mid range which is what I would consider more usable with this application (truck).....if this were a car with an LS powered 6.2 like a corvette or camaro it would be 1 7/8 every time as there isn't enough of a difference not to take advantage of the few extra hp/tq in the mid/upper rpm's.

Neumonic Posted July 3, 2017 Share Posted July 3, 2017 As long as you don't tell me Shane Hinds or PBJ I'm all ears. Sent from my iPhone using Tapatalk I hear ya there!! Dave Steck did all my tuning in the past, I'm sure your aware that he moved to TX but I know he offers remote tuning as long as the person has access to HP Tuners or knows someone that does. There is a local guy named Jake Batz that is a bit of an unknown, he is good with NA applications but I'm not sure if he has the experience with tuning transmissions? I will reach out to him to see what he says and let you know. Have a great 4th! Quote Link to comment Share on other sites More sharing options...

What a bummer when he moved, but man was I glad to hear that he's starting tuning for us peasants again. Dude is like a wizard. I've actually heard a little about Jake. Shoot me a pm when you hear back from him. Thanks! Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
L86 All Terrain Posted July 12, 2017 Share Posted July 12, 2017 300whp and 330lb-ft at 1750rpm with a naturally aspirated small block on 34's is kind of funny to say the least, those are above peak numbers on the early Gen III-IV LS family 5.3L. Congrats man. Quote Link to comment Share on other sites More sharing options...
elementaltoad Posted July 20, 2017 Share Posted July 20, 2017 Nice numbers! Makes me wish I went with the 6.2. Quote Link to comment Share on other sites More sharing options...
L86 All Terrain Posted July 21, 2017 Share Posted July 21, 2017 (edited) Will you be doing anything else to the truck or just basic bolt on's and tune? Edited July 21, 2017 by L86 All Terrain Quote Link to comment Share on other sites More sharing options...
NemesisC5 Posted July 30, 2017 Share Posted July 30, 2017 Better results than I expected, congrats! I'll be doing the same to mine hopefully this winter. - Stock wheels / tires: On a 2WD street truck changing from 20's to 24's I saw a friends truck drop 30whp on back to back pulls last November, however that was on a 5.3 with same mods as yours w/E85. I'd think your 20x10's & 34's are likely costing you 15-20whp. - Regarding a post above referencing E85, the 6.2's don't have as high a CR as the 5.3's so the gains won't be as much which explains why GM doesn't have an E85 tune loaded. With a belt driven intake manifold, E85 would deliver the goods ! Quote Link to comment Share on other sites More sharing options...
chevydeth Posted May 21, 2018 Share Posted May 21, 2018 hmmmm I’m wondering what I’m put down then, afe momentum gt intake, ported throttle body, and blackbear e85 tune Quote Link to comment Share on other sites More sharing options...

I'm curious as to why the 5.3 is rated from GM to produce more power with E85 and the 6.2 is not (especially with the higher CR). Quote Link to comment Share on other sites More sharing options...

That’s probably why it’s not rated higher with e85. Quote Link to comment Share on other sites More sharing options...
