Shame you weren't in Birmingham last week for Porsche Parade. We sold x4 718 4.0l Accessports in the three days we were on site and even installed them all at our separate install booth in the downstairs parking garage. Bottom line, we were just as shocked as everyone is when they initially see the gains from just ECU tuning on these motors. The stage 1 93 gains are reliably 35-40whp on the GT4/Spyder and 55-60whp on the GTS due to the artificial restriction tuning by Porsche to depower the GTS stock. Which, extra nugget of info, unlike previous iterations where they simply didn't open the throttle blade fully despite 100% pedal input, Porsche complicated the restrictor process this time by fluctuating the throttle blade during a WOT pull. Took a little bit of extra time to sort out that shenanigans but if you go look at our dyno plots you'll see our Python Green Cayman GTS 4.0 technically eeked out a few extra HP over the Guards Red Spyder in final testing, chalk that one up to motor power variations from the factory. And yes, we owned both cars simultaneously specifically to confirm they would produce nearly identical results when tuned, which they do.

As for the warranty topic- it's been beaten to death over and over and over and everyone simply has to choose their own level of risk. For those who don't think 40-60whp is worth it in an NA motor... <shrug> ...that's your choice. As anyone who has asked me in person at any event we attend has heard multiple times, and can go find typed here just as many times, we do not sell the AP as a warranty friendly device, nor are we in the business of promoting warranty fraud, so no, we do not adjust or defeat any flash counters or any other potential ECU tuning detection protocols. With that said, when properly uninstalled from a Porsche the previous AP installation will not cause some magical super red screen of death to appear the second a technician plugs in a PIWIS4 to your still in warranty car. The reality is they have to go digging to find any information regarding flashing history and even moreso, they need to be given a reason to. Our recommendation is, and always will be, to discuss ECU tuning specifically with your preferred Porsche service center, preferably with the Service Manager directly as the DEALERSHIP is who sold you the warranty, and will be the first to decide if they'll cover any repair under warranty. When in doubt, I strongly recommend supporting dealers who are active in your local autox, HPDE, and club racing events as they are generally going to be the most understanding and accepting of modifications, including ECU tuning. We actually have more franchised Porsche dealerships as authorized COBB dealers than any other manufacturer we support and that speaks volumes to each Porsche dealerships ability to make their own decisions on what and how they sell along with their views on the quality of our product.

As for competitors- every single one mentioned in this thread is a solid choice. Each has benefits and negatives, just like we do, and there are no secrets in the aftermarket calibration world once someone's tune hits the market. The idea that one particular company's product is going to make significantly more power than any other company's product that has been out for more than ~six months is totally unrealistic. If you're trying to decide on which product to buy based solely on the notion "this one makes the most power" then I regret to inform you, you're more than likely going to end up chasing that goal endlessly. Instead, purchase the product you feel checks the most boxes for your particular application and enjoy it, write a review post about it, let others hear your honest opinion. We most certainly welcome the feedback and the competition.

Speaking of feedback, please remember we do offer our 30 day money back guarantee and have for over 20 years. Additionally, if you're at a multi day Porsche event where we're on-site, we'll more than likely be selling an installing APs there. We are more than happy to offer you a "test drive" of an AP. We're happy to install an AP on your car for a day or two to give you a chance to test it out and decide if you want to buy. We've had customers in the past do that for some of the official drives, for autox events, even for the HPDE. We strive to provide the best customer service in the industry and it's very important to us that you're fully satisfied with your purchase and if letting you take it for a spin will help with that, then we're all for it.

Thanks!
