Just dyno'd my 2011 Ram...Stock tune vs HemiFever's Tune

I knew there were some pretty big gains I felt when I was data logging for Hemifever to get my custom tune just right....this just reconfirms what I was seeing from the logs.....

Pulls were in 85degree weather and 24% humidity


I must say these newer Dodge rams are hard to dyno espically if you have a Torque Converter...I wanna say I probably went through close to 15 pulls because even on the stock tune it just wanted to pull pretty funny on the top end maybe because it was just on the rollers vs the street. After talking to HemiFever (Sean) he told me something about a short runner valve that opens on the top end that usually makes late model dodges hard to dyno.... He might need to chime in to explain it a little more. I do have a couple of vids but I'm sure I those wont go up until tomorrow (gotta go to work tonight). Next up will be some track time's (maybe in 2 weeks) on these 22" wheels....depending on what I run/traction I might just buy some 17s or 18s with DRs for the rear.

So 370 vs. 304 HP and 365 vs. 309 torque?

Wow. Your drivetrain loss is like zero. That's awesome.

Can't read that very well.....what was the difference?

DT makes all images upload why to small.....

My best stock run didn't get saved it was around 315hp/320tq (saw it in the first couple vids I took)....I did noticed on the stock tune I was running pretty rich (low to mid 11s) and with HemiFever's tune I had an a/f ratio of 12-12.2. I guess with the stock tune the computer can't adjust the A/F ratio properly without tuning with this many bolt-ons which I'm sure ended up hurting my baseline stock tune numbers. It's pretty impressive what HemiFever can do to optimize the tune to fit your truck vs a canned tune made for everyone.

U picked up that much HP with exhaust and intake and a tune :|

thats insane :| !

Great numbers and great gains.

How you liking your JBA headers?

What is that spike towards the end?

I believe that's a gear change. Mine had that too.

That's what I was thinking. So his peak HP is 330ish?

his dyno says 370 hp and 365 tq

I've had them for about 6 months now and they are definitely alot better with a tune.


Thanks yall.....obviously the gains are there as you can see it throughout the powerband vs the stock tune. Like I said out of about 15 pulls I did they had that funny dip and lose power (on the dyno only and not in the street) and comeback like crazy causing a spike so who really knows what I actually put down as peak numbers. All I need now is to get some 1/4 mile slips...the numbers that really only matter.

Looks like you are making a true 335 RWHP if you smooth out the weirdness on the dyno, which is a very nice gain for your mods over stock.

Exactly. The power gained through the tune is nice which ever number it is!

Here they are....there not the best vids but pretty decent.

These are about 1/2 the dyno pulls I di d.....either I didn't record them or the dyno operator/actually machine/maybe my Torque converter was causing issues getting numbers down.

Here's a picture of a 0-60mph pull I did before work today.....bare in mind I was on an pretty crappy road, it is 83 degrees outside, and pretty much on a cold start.

Glad to see you haven't given up on the truck just yet. Now go out and get some time slips!

Yeah I was really close bro but I'm glad I didn't.....I just don't know how much farther I'm gonna take it performance wise, right now I'm stock piling a boat load of cash for another go fast project for the spring.

I got off of work this morning and decided to make an 0 to whatever pull for you guys (it ended up being 120 lol). I got pretty excited when I looked down at the speedometer and accidentally hit the stop button before showing my 0-60mph time from my trinity... there's a link towards the end of this video to see it.

The pull was on a pretty decent road but it did have a slight incline till about 70...FYI I also did do a 2 sec burnout before the pull which helped me hook pretty easy.



I took a picture of the 0-60 from the trinity.....not bad for a Crew Cab on 22" wheels!

nice gains. ask them for a graph with RPM across the bottom not MPH

The whole dyno experience wasn't good I had a hard time getting decent pulls (I'm thinking the TC didn't like being on the rollers). When I was looking at the hp vs rpm on that dip and spike my rpms pretty much dipped/disappeared for a brief second and came back from the spike. I'm not worried about my true numbers, all I know my truck is running a hell of a lot better especially if you compared it to my 0-90 pull I recorded back in April....Looks like I've gained 2 secs from 0-90 when comparing the two. I will getting some slips here pretty soon, hopefully on the 7th with a bunch of the other guys that plain on hitting the track in the Houston area.

Here's the old run from back in April
