I have a 2016 A8 and have the BMS Filter, Ported Mamo TB, and Borla X-pipe still on stock tune. Not sur how much more power I added it hasn't been on the dyno yet. You will see various reports on how much power these three mods add some say a lot some say not much at all and any were in between. The best example is there is a video were a shop did a test on three X-pipes the Borla, Corsa, and a 3 inch Titanium the shop made. Some say the x-pipe doesn't add much at all just better sound but after I saw this video I don't know how they could say that. But there is a thread on here were the guy did the same three mods and according to the dyno didn't really pick up much power. Check out the Video

That video is the reason I chose to use the Borla pipe. I drove the car 80 miles today after installing the T.B. and the Burger filter. No codes or problems. First thing I noticed was better throttle response on tip in particularly from a stop. Almost all of the throttle hesitation is gone in transitions from off throttle to on. Intake noise or roar is greater. The first half of the drive was at senior citizen pace on KY backroads (within posted speed limits) just to let the ECU adjust to changes if in fact it actually does. The second half was on interstate 71 between Carrolton KY and Louisville. Hammered the car to see if it would throw a code. Made 3 full throttle runs from 55 MPH to over 160 MPH and several more from 55 MPH to over 125 MPH with no problem codes. Temperature was 89 F and engine coolant went to 210 F running a steady 90 MPH. Butt dynos are subjective and mine is no better than anyone else's, so my subjective judgment that the car is making more HP and pulls harder is just my opinion and will have to be verified by objective dyno data. I will schedule another dyno session which will probably be next Monday or Tuesday and that will give me more time in the car.

Update: the next dyno session to test what the Momo T.B. & Burger filter did (no tune) is scheduled for next Monday morning at Dynosty in Louisville. Will install the Borla X pipe next week and dyno session is scheduled for the following Monday morning (no tune) ay Dynosty. The fasterproms 2.31 pulley just arrived. Only part still on order is the 160 F thermostat and billet housing.

This video is what sold me on the Borla x-pipe as it's also a 17 M7 like mine. Their stock baseline is almost identical to my stock baseline with SAE 5 correction. In retrospect they didn't actually drive the car any significant amount of time after installing each one to see if the factory engine calibration would adjust for it over time. Maybe resulting in a loss of any short term gains shown.

This is the first dyno runs on my 2016 ZO6 (stock)

See dyno sheet below 2nd dyno session overlay of best run from 1st dyno session.

The image size above did not allow enough room for comment. 2nd dyno session & best run from first dyno session with install of Burger filter & Mamo T.B. did not produce much additional HP & TQ. Peak HP was 555.03 & peak TQ was 617.89. HP peak moved up from 5,770 RPM to 6,060 RPM. TQ peak moved down from 3,680 RPM to 3,490 RPM. A/F curve shifted slightly probably from MAF reading increased airflow.. Nothing like the increases shown by either Burger or Mamo. Run conditions today were almost identical to 1st dyno session last week. This is why I wanted my own independent corrected dyno data from the same dyno & technician. Next dyno session will be with addition of Borla X pipe. No tuning will be done.

It will be interesting to see what if anything the x-pipe does. I think you're about to prove that the 15-16's being more "no tune" mod friendly than the 17+ is not true. The stock engine calibration just adds more fuel for a rich A/F ratio to keep power around the same level as stock over time. If one wants to get a real permanent gain from these mods a tune needs to accompany them.

. Thanks for posting this and great info. Finally some true data on just what the filter and TB do kn the stock tune. So much for those claiming 30-40 hp gains.

likeaboss

It's awesome he took the time to do this. I had similar thread about my 17 with about the same results,that got deleted because of members squabbling. These mods without a tune are just a placebo effect no matter what year you have. Slap it on and do a quick dyno and you'll probably see a gain until after the stock engine calibration has time to correct for it.

Scooby this is just my own data. I am trying to get the most consistent data I can using the same dynojet dyno with a competent operator and using STD readouts for each session. I am also driving the car at least 200 miles after a new modification, and this may be key to the results I am seeing, vs what you have read elsewhere. This may be an indication that the ECU is readjusting to compensate for the change over time that may not show up in a back to back test. I now suspect that a full tune may be required to see the results shown by suppliers who are testing back to back. My car is a 2016 ZO6 auto. Next mod is to install the Borla mid pipe, drive another 200+ miles and have the car dyno tested again hopefully next Monday.

The thread likeaboss started on his 2017 car was what convinced me to take the incremental mod route with dyno sessions after driving at least 200 miles instead of doing back to back testing. That was a good thread that got bounced because of squabbling among other posters, not likeaboss's problem.

Glad to see this, but if the TB and filter fix the throttle hesitation I think it's still worth it.

I will be interesting to see what the x-pipe does based off of my post #21

3 Z06ZR1

The numbers are in STD and not SAE so you could get a new print out from the shop with SAE numbers the STD numbers are higher than the actual SAE numbers everyone uses.

Me, too. I have a '17, Z06/Z07 M7 with these exact parts sitting at the house to be installed. I'll be happy if the tip in hesitation is fixed, too. I had a C6 for 10 years with ported TB, ported intake, etc and it was snappy. I've had the '17 for about a month and the hesitation is the only gripe I have.

RegnaR

Haha I have the x-pipe and filter, just need the TB and have had my 17 for about the same amount of time

likeaboss

If your 17 is anything like mine you're going to have the same amount of power as stock and running really rich with all three mods.

RegnaR

But will the partial throttle be better at least??
