New Custom MHP v3 tune - 482RWHP/444RWTQ(93 octane)
 

Recently I switched to a revised version of an MHP tune, this was the tune I was running at Atco on Dec. 5th when I ran a personal best of 11.29 @ 124.72. I was extremely happy with the results but like many I’m always in search for more horsepower. That being said, Andy from MHP approached me regarding a custom dyno tune. There was one minor problem, the custom tuning would be done in Ohio, a 10+ hour drive from New Jersey. I’ve always desired a custom tune and regardless of the distance I decided to make the trip. To me, my decision was justified based on the results.

A Dynojet 248 dyno was used on all pulls.

Baseline numbers: 465 RWHP - 422 RWTQ

Custom Tune numbers: 482 RWHP - 444 RWTQ
30+ RWTQ numbers in the midrange.

Honestly, I think the numbers would have been higher because only one fan was used for all pulls. As many know it is very difficult to replicate actual wind speed on a dyno.

Drivability, acceleration and shifting have all been improved from prior versions. The vehicle pulls harder than ever which I attribute to the extra 30+ RWTQ in the 3000 to 5000 RPM range. MHP’s new tuner did a tremendous job on my vehicle and I cannot say enough how different the car feels from before. Power seems endless and on tap at every rpm.

This has been one of my goals from the very beginning and I recommend it to all owners if the opportunity presents itself.

Also, just to note, we swapped out my RENNtech air box for the stock air boxes and the RENNtech made more power on the dyno which backs up my data from previous track results.

I want to thank MHP and all who were involved in setting up and executing this event. It was nice meeting everyone. Kent(AMGFTW) and Mike(dodger63) car were also there and put up awesome numbers too. I was never a huge fan of dyno’s but they can be important for determining gains and for nailing down air/fuel ratios.

This new MHP tune is highly recommended.

That is a long way to go for a dyno but the tune on the dyno looks like it made it worthwhile. The numbers look great and from the sounds of it you are very happy with the results. With all the drama lately it is nice to see some very positive results from MHPs new tuner.

Congrats and I am happy that it turned out so well for you. :y

Yes, it was a long way and I was seriously considering not doing it but a close friend offered to trailor me and I accepted.

MHP's new tuner is spot on.:y

Thanks for the informative update. I got an OE tune coming in the mail now and may send me second ECU to Andy in the spring for his revised work.

Wait! Why Wasnt I there!!! Damn!!!!

You will be extremely satisfied.

:D

You missed out buddy.

Too bad I'm selling my car. The next one though will be MHP!

WOW!! 17 whp extra and 22lb-tq in top of an already best tune. 30lb-tq extra in the midrange!!.. I can't wait until I get my revised tune/files as well.

Congrats Petro.

Thanks Andy!!

That is some serious N/A power. Can't wait to see the new 1/4 mile results

Does anyone have some dyno results comparing 91 and 93 octane fuel maps?

Say I got a 93 Octane tune done. Does the ECU have enough ability to retard timing if it senses knock if say I had to fill up with 91 octane once?

Didn't know your were selling. What are you getting next?

Thanks, I was really impressed.

Me too.:)

Yes you would be fine

The differences would be mininal at best in my opinion.

+1

Just don't put any regular(87 octane) in there.

Nice numbers mike!

Coincidentally your baseline numbers are almost identical to my car's latest run on dynojet 224, SAE corrected. I'm assuming your results are also SAE corrected.

Get back to the track!

Thanks Eric.

No, numbers are not SAE corrected. All I'm interested in are the gains, which were extremely satisfying, especially in the mid range.

Congrats Petro
As long as u happy with the results that's what matter.

Nice gains!!! :y

Thanks Hagi.

Thank you.

Thats excellent stuff. That new MHP tune looks pretty solid. Where did all the improved gains come from primarily? is it from AFR or did they add more timing as well?

Congrats, Mike! You're so close to 10s in your current setup...and that's so impressive given the fact you have a full interior.

You should come down to MIR with Dodger next time, shoot for tens! :zoom:

I know nothing when it comes to tuning these cars but I would think it was a little bit of both.

Also, the RENNtech air box made about 10-12 RWHP more than the stock air boxes on the dyno and shifted the curve to the right a little.

Thanks Jason.

My goal is to run 10.9 or faster with full interior and no wheel changes.

Next track rental. :y
