Great. Don't make any changes to your current tune. We will just run it as it is. Just PM me your phone number and someone at the office will call you tomorrow to make dyno arrangements. Just keep in mind that I will update this thread with results (dyno, datalog, extracted ROM file).

Cheers,

@DeliciousTuning @R/T Tuning @sales@delicioustuning.com what do you think?

No problem, I'm absolutely fine with you posting our findings. I was going to say that I'd do the same if you weren't.

I'll delete the thread too if we find it to be something completely different.

How refreshing to see someone (Shiv) standing behind his tune and recommending an independant test, which he will pay for. This is the kind of customer service I like to see and I based on my experience with the OFT tune so far I doubt that the problem is with the tune itself, mine has been excellent. :cheers:

Problem seems reproducible and since it can be heard outside the dyno AND tune doesn't seem like it has been edited. I'd say problem is present but doubtful it has abutting to do with tune

....also 205 crank can probably be hit with stock car and filter

Going to leave this thread alone until we can narrow down the problem. What's odd is, I don't feel any power loss when driving hard. I've asked Shiv to drive my car for a 2nd opinion.

I can't see how you wouldn't notice such a dip when driving tbh, and if you don't feel any loss of power, it suggests something was happening with the dyno itself? Keep us posted. :cheers:

Their is nothing wrong with this half million dollar MAHA dyno. This was installed and calibrated by MAHA directly and routinely checked as it has a secure direct connection with MAHA.

There is nothing wrong with the operator. He has a right foot, he placed it on the pedal and pushed it to the floor. Pretty hard to mess that up.

We tune on this dyno routinely and it is a whole new world of tuning when on this dyno. I have been lucky enough to tune on it multiple times and half to say it is the best dyno facility I have ever used, and the people are extremely professional.

Here is a video we did last time we were there. It is a 43 second pull in 5th gear starting at 1500 RPM. No problems and you can hear it run smoothly all the way through the powerband.

By the way we just ran a 13.79 at 99.45mph with the help of this dyno on our Stage 2 E85 tune. Pretty sure that is the fastest NA full FRS/BRZ in the world right now. Thanks Mann Engineering and MAHA.

20hp and 20ft loss for 500rpm should be extremely noticeable on the street. Something so severe looks car related to me. Pulleys? Resonance?

You have the roms and software to go look at the tune to see if there's anything in 4600-5000 rpm range to cause it. Why wouldn't you do this?

I'd prefer threads like this not get deleted, whatever the outcome, instead of generating fear and doubt and then disappearing in a whisp of smoke, which incidentally seems like a lot of people in the tuning industry like to do (or whisper in other people's ears and send them forth to generate fear and doubt).

I agree with this. Regardless of the outcome, this thread shouldn't be deleted as it will surely help others in the future who ever find themselves in the same or similar situation.

Could it just be that the P&L header requires slightly different cam tuning to produce max torque accross all rpm?

Subbed as I have OFT and about to pull the trigger on the same header...
