3.6L Update on my V6

Been a long time since I posted here, so I thought I would give an update on my latest car project. I have a 2017 SXT Plus Challenger with the 3.6L Pentastar engine. I added a supercharger way back in 2020 and since I live in the Fargo area there wasn’t anyone experienced in tuning it. I had it remote tuned by a guy in Texas. Had no issues, and made a 0-60 run of 4.35 seconds and a 1/4 mile run of 12.3 seconds on the Dragy app. A friend of mine works for Minnesota Performance and thought they could do a better job of tuning, so I dropped my car off there while I was traveling for a week. I had a previous dyno done that came back showing I’m putting 438.9hp to the wheels. I was nervous about the new tune and dyno, as they call theirs the “heartbreaker dyno. Apparently most people get a smaller number than they got from their prior dyno runs. I was quite happy to find out that after the retune the dyno on my car came back at 455whp and 388 torque. Couldn’t try it out though yet as it’s been raining. May need a new belt and belt tensioner as I am occasionally getting some slip, but otherwise I am ready for the summer car show season.

 

Who in Texas provided you with a remote tune?

 

Demigod Tuning.

 

Mario emailed a E85 tune in 2021 for my stock 3.6 Challenger AWD GT . According to the dash my best 0-60 was 5.3 Though it seldom I do that..

 

I use the Dragy app, which is accurate to 1/100th of a second according to them. I ran a 4.35 on the Dragy and the car timer said I ran a 4.2. I don’t think it’s very accurate.

 

What brand of supercharger do you have?

 

Ripp Heritage Edition

 

Haven’t posted here for a while. Been doing lots of car shows. Had one an hour away from home yesterday that 516 showed up at. Got 30.3mpg at 75mph on the way there and even took the time to do a 1/4 mile pull.

 

Wow you put a lot of work into that V6 Challenger, impressive numbers too.

 

'Stock 3.6' with an ethanol conversion kit? What percentage E85 are you able to run and which device did you use to administer the tune?
