993TT Greddy Profec Oled install procedure:
- Utilize Orange Lead from pin 1 of Central Warning Cancellation Switch in Center Console for 12v key on hot.
- Pin 4, Switch for Sunroof (Brown Wire) for Ground.
- Mount controller on right side of center console, if possible, with face of controller aligned with face of console. On top, just under the ashtray also works very well.
- Route Harness through the console, under the carpet to the left of the shifter, under the drivers seat then follow the main DME / Engine Harness back to the engine bay.
- Disconnect the factory vacuum lines from the wastegate solenoid, they will be re-used for the profec.
- Connect Port 1, Normally Open (NO bspec2) port to the port off of the throttle body.
- Port 2, Common (COM bspec2) port should go to the line that runs down below and T’s off to the w/g actuators.
- Port 3, Normally Connected (NC bspec2) port should go to the line that runs towards the front of the car and vents into the Y pipe at the back of the engine, just upstream of the mass flow sensor.
- Be sure that all the little red plugs are out of the solenoid!
- Tee off the fuel pressure regulator vacuum line and route the hose along with the w/g controller harness up to the head unit. Preferably, use hard plastic line that won’t be accidentally crushed or cut easily.
- Route the profec wiring harness forwards, just to the left of the drivers side shock tower.
- Then, driving the car, with the w/g controller either all the way down, or off, it should regulate at the spring pressure of your actuators, or about .4->.5 bar or .7->.8 with upgraded actuators..
- From there, turn it up 5% at a time till you get the boost you’re after in low, then repeat this in high.
- The factory gains, start boost, etc. are good for starters. You can tune the controller for slightly quicker boost response by increasing the gain until it spikes the boost a little bit, then turn it back down till it does not do that. You can do the same thing with the START BOOST setting.

Trevor Morris2024-04-22Todd is the ultimate godfather of Porcshe! His knowledge and informative videos have been invaluable to me as a Porsche enthusiast. I'm incredibly grateful for his expertise and guidance. I had an intermittent problem with my 996tt that has plagued the car for 6 years, no shops were able to figure out the problem. I emailed Todd and he narrowed it down within a couple emails, and sure enough he guided me to the problem and it was a simple fix in the end. Not to mention Todd's tuning skills are off the charts, as the car also traps 144mph in the 1/4 mile. Keep up the fantastic work, Todd!
Chris Roundtree2024-02-19I wanted to thank Todd at Protomotive Motorsports for going above and beyond when he helped me sort out a problem with a product that I had purchased from another vendor. Todd seems to always have the knowledge to put together the best combination of parts to make any model Porsche not only go fast or handle better, but do it reliably. He always answers the phone. In the rare event he doesn’t pick up he gets back to you within twenty four hours. Emails get responded to just as quick. I really appreciate having some like Todd available when working on any Porsche as you know he has a proven setup to satisfy any goal. Thx Chris
Antreas Smilas2024-01-22Super in every way..2 years now in ecu and tcu perfect power delivery ,reliable,and fast as mr Todd promise in number...i can say even i draggy was the same numbers as promise to achieve with this set up.
Taylor Berg-Kirkpatrick2024-01-04Todd has got to be the world's expert in forced induction Mezger Porsche engines. I've worked with a bunch of mechanics, tuners, engine builders across multiple Porsches over multiple decades... and Todd has been the most helpful and knowledgeable of the bunch. And this has even been true while working with him remotely! (I'm in CA and he's in AR.) Just by looking at my logs and hearing about my engine rebuild, he's been able to diagnose stuff that in-person mechanics have not been able to. For example, Todd was the only person looking at my car to suggest a problem with a BRV could explain some of the weird behavior... following his advice, I dug in myself... lo and behold, torn BRV diaphragm on bank 1! Wow! Further, Todd has the most experience tuning these cars of any tuner I've worked with. Tune is absolutely solid and safe. Very very confident in his work!!! Absolute strongest possible recommendation!!
N K2024-01-04Todd and his team are true professionals and they always provide excellent customer service, quality parts they sell and very reliable engine builds. This is very rare in our industry today. Great job Protomotive!
raphael wirth2023-05-29Todd est l homme de la situation…. Des difficultés ou des problèmes pour régler le problème? Todd trouve la solution malgré la distance ( je suis français) Merci à lui et son équipe pour leurs conseils … Maintenant mon 997 turbo fonctionne à merveille et est un véritable avion de chasse! Je recommande a 1000% !!! À bientôt pour d autres évolutions !!!
Adam McGregor2023-04-05I don’t think there is a better shop to shop entrust your Porsche to then Protomotive and the Knighton’s. Just search there name with 993 and you can start to get an idea of their storied history of building monster but reliable 911 Turbos! I have over 12 years and 30k miles (street, autox & track) on the Protomotive set up on my 997tt and it has never skipped a beat!
Piotr L. Pawlak2023-04-05Unfortunately they could not resolve my issue, but Todd tried very hard to find some other resolutions. He was very helpful and responsive.
B W2023-03-23Todd is by far the most professional and knowledgeable Porsche person I have ever worked with in my life and I have had many cars and have been doing this for over 20 years. He not only knows how to overcome every single problem, but also knows how to explain exactly what he is doing and brings the car to a point where it feels like stock even though it has double or triple the power. If you go anywhere else you would be making a mistake
Alex May2023-02-20The engineers at Protomotive are absolutely the best. They performed extensive work on my Porsche GT2 and I literally could not be happier. Their work, attention to detail, problem solving and communication with me were all next level. Customer service is remarkable. I had a question while at the track, on a Saturday, and Todd immediately responded to my questions. Class act.
