Well, I was disappointed at the gains initially. I dynoed 280 stock, and after intakes, hfc and catback, I was at 286. I got it tuned and am now at 299. I'm wondering if its the hfc or the takeda long tube intakes. I'm not so caught up on peak hp #s, but curious why my gains were so low. And as far as torque goes, I went from 234 to 246

You picked up almost 20 HP with easy bolt ons... that's not low gains lol

NBZ34 02-21-2013 09:43 AM

And a tune. Like I said, I was more disappointed before the tune... Which was needed anyway because my air fuel ratio was rich

Ah.

Well if you drove the crap out of it for a few weeks then re-dynoed, you'd be closer to your post-tune number because the ECU would have had time to adjust.

I never pay attention to or give any credence to "pre-tune" numbers because they don't really matter. A tune should (IMO) be automatic when you do anything beyond put a CBE or drop in filter on your car.

Again, my opinion (supported by your experience), so to each his own. Glad you were able to get it cleaned up, you'll probably pick up another couple WHP over the next few weeks as the ECU fine tunes as well.

Thats what I was thinking too. Love the sound though and the butt dyno definitely approves!

Look at my mods list and then come talk to me about disappointment. I base lined at 270.

First and foremost to properly gauge where you are the car needs to be tested in 5th gear. That is the 1:1 for both the 6MT & 7AT. If it is tested in 4th, the overall numbers will be down about 3-5%. I am not saying it was performed wrong but just double check.

That being said with the mods you have the numbers are low all depending on what type of dyno your car was tested on. Every dyno reads different and some are heart break dynos. Generally the Mustang and Dyno Dynamics dynos read the lowest. The Dynojet is the most commonly used in the industry and the numbers are pretty standard. The Dynapaks generally dyno high however are one of the best for tuning.

We have always performed our testing on a dynojet. On a 6MT we usually dyno right around 280 RWH & 235-240 RWT. Now without a tune and performed with many cars over the years, the average is right around 310-315 RWH & 255-258 RWT. This is all in STD mode on the dyno. These numbers I am giving you are for our CBE and HFC's with stock intakes.

All of this being said, once you put 150-200 miles on your car the ECU will have cycled through and adjusted for the new mods. You will feel a difference throughout the entire rpm band.

If you have any questions at all, please do not hesitate to call me directly.

Thank you, Tony

Thanks Tony. The numbers i provided were the STD readings from a dynojet. I thought the pull was supposed to be in 5th as well, but im pretty sure it was done in 4th.. I have an AT.

argotech,

Thanks for the feedback. Your drivetrain loss is also 5%-7% higher with the AT vs. the MT. Your overall numbers will be lower. It seems like your baseline was done in 5th and your current test was performed in 4th. If that is the case you do not have an "apples to apples" comparison.

Please keep me posted to what your finding are.

Thanks, Tony

It was 4th last time too.. last march. Evidently 4th is the gear to run in up to 125 mph for n/a cars... or so I'm told.

The overall mph is not the issue. 4th is not 1:1, it is 1.412:1 to be exact and for the 6MT it is 1.271:1

Thanks, Tony
