You have a 6mt right? What gear did they do the dynos in?

ClemsonWill · 05-21-2011, 06:09 AM

Yeah, 6mt. 4th gear pulls. I did some 3rd gear pulls with the first dyno. Lost about 5 hp.

You need to dyno it always in 5th gear! That is your 1:1 gear ratio. This will yield the most accurate numbers.

Now once you put about 100-200 miles on the car you will notice the ECU has adapted. The throttle response and pull throughout the entire RPM range will feel like a completely different animal.

You should never get a CEL. The only way you would is if you had an exhaust leak coming from where the header meets the engine, or a fouled out O2 sensor!

Enjoy it all and do not hesitate to call me directly with any questions that you may have. Again, thank you for your business, it is greatly appreicated...

I didn't realize that. I have always done 3rd or 4th. I'm not sure how comfortable my dyno guy will be with 5th gear. But I will ask him when I got back for a tune.

ChipsWithDips · 05-21-2011, 07:57 PM

Yep, 5th gear is 1:1 for both manual and auto trannies.

Comfortable or not, it is the only right way to do it! That chart above is very useful. I need to save that to my computer!

Here's the video... you'll see that I still had 1k rpm left to go before redline, and it topped out at 140, so he still could probably make it to redline before 155...

And thanks for that image, Saved as well!

Yeah for my 7AT, my baseline dyno was done in 3rd gear (dunno why) but it only gave me 248whp/210tq... Then after getting the headers/cbe I had another dyno, this time they did it in 4th and I got 283whp/230tq... I wanted them to do a dyno in 5th gear like what's been recommended, but when he did the dyno (you can check my vid's) he took it to 6500rpm (140mph) then stopped because he said he didn't wanna run the dyno that high...

So I don't really know exactly where I stand, I think I need to take it to another dyno... It just sucks because I can't get an accurate estimation of how much power I've gained due to inconsistent dyno's...

I did and we will work something out. I will take your deposit from the headers and most likely apply it towards the custom exhaust. Luckily for you, I have a local car here that I can build your exhaust off of!

I will be in touch shortly...

Thanks, Tony

Woohoo! All I need to know is total price and I will send it your way.....

Mine's installed now (blblack on your list). Had the install done at Baker Tuning, and that turned out to be an excellent choice

. I really liked the sound of my FI CBE w/ short headers and HFCs before, but it's really a whole new animal now with FI LTH + FI CBE. I'm not sure how to describe the change in sound... even more exotic than before, and much burbly-er? A little bit louder all around, but still reasonable on the street.

Do you have the SS or CF cans?
