I have added a JCR Valved Center, JCR Race Cats and Tuned a Stage 2 with M-Engineering on my 2023 TTS. What can I expect for HP and TQ? I know what M-Eng told me and I just want to know if anyone has dynoed this setup? And is there anywhere in Alberta, Canada to get the car dyno'ed? M-Eng said 735whp and 700ftlbs. Does this sound right? What do most use for drivetrain loss? 18%? By my math that is 867 crank hp. Does that seem high for stage 2 (200 hp over stock for a tune, exhaust, and link pipes)? Where am I wrong.

I could only get 746 whp thru 100 cell race cats, I removed the cats and went over 800, that's with big turbo's, my car was dyno tuned by M Engineering at World Motorsport in Cali in 2021, have exhaust, intercooler as well

Dyno numbers do not mean anything. All a dyno is good for is tuning and seeing the difference between setup A and setup B, the delta between the numbers or gain in power. For example, if you dyno'd the car stock, did stage 2 then dyno'd it after, you could see the increase in power from stock to stage 2.

What really matters is your 60-130mph time and 1/4 MPH, those are true tellers of performance. As your car performance increases, these metrics will increase and show you the power its making. You need to get a draggy, you can order them online, or M Eng also sells them. Might be some used draggys on Kijiji? (Another thing to keep in mind, DA (Density Altitude) which is the density of the air in the environment. A low DA vs high DA run will be quite different.

For example, I was able to do a 5.6 to 5.9 60-130mph with stage 2, no cats however. My 1/4 mph on the street was always around 140mph.

If you want to dyno it still, my buddies own a shop Acceleration by Kingsway, you can dyno it there, but their dyno reads low so it won't be any hero numbers. However, I did all my tuning there so you could compare stage 2 with stage 4 (me).

If you haven't, you should order the Do88 Turbo Inlets and BMC air filters, that will help the turbos breathe and bring in air easier.

On our Mainline ProHub Dyno at our facility in Pompano Beach, a Stage 2 992 Turbo S usually lands around 650whp or so on 93. They will baseline stock in the low to mid 500's. Those numbers can change based on DA and octane of course. The dyno mentioned at World will read a bit higher than our mainline. But yes, it's the before/after delta that matters the most.

My 997 turbo with intercoolers, 73mm GT3 plenum, larger AWE turbos and full exhaust (200 cell cats + headers) was 600whp 93 oct and 630whp 100 oct on a Mustang dyno. 650whp on 93 with just a tune and slip on exhaust is just amazing. I have yet to run a full 60-130 yet but plan to do so this weekend finally lol. That will really be the telling metric. Hoping for high 5's to low 6's (feels like it is)

I never got a stock 60 -130 time but after exhaust with 200cell cats and M-Engineering tune it went 5.8x with a slight spin and then letting off around 125 for a car in my lane. I watched a video of a guy at the track and his stock one went low 10s @ 135 mph and 60 -130 was in the low 7s.

Your car will trap 140mph with that 60-130 time, maybe 141-142 if you can get the 60-130 down a bit more.

The thing with TT cars is top end mainly changes with bigger Turbos. The limits of the factory Turbos are easily seen/ felt up top, but those smaller Turbos are also what make it a rocket off the line.

The TTS is a factory 9.9-10.2 car trapping in the high 13X. If not hitting those marks tuned, then there needs to be a chat with tuner.

I did 10.29 at 136mph stock and 9.9 at 140 with stage 2, both on pump gas 93oct.

Stock 60-130 times quoted are all over the place. Some say low 7s some say 6.7. The difference of 0.5s is around 80 hp. I dont know how there can be so much variety. I always assumed TTS was a 6.7-6.8s car.

DA and fuel.

mine was 6.6 to 6.7
