My S555 4Matic (it’s now 5 better!) climbed past 70MPH so fast that I frightened myself in between giggles. I zipped up a nearby curvy (and empty) two-lane that I used to struggle to drive at 60MPH in a Ferrari. Your up-tune caused nearly uncontrollable giggles. If it doesn’t make me giggle it ain’t enough. I’m proud to display the Pressertech badge! And I def will send you dyno results when available – should be interesting! Truth told, I really don’t care what the dyno says, it’s what the seat of my pants says that matters. I don’t ever wear a hat or shirt that promotes anything – but you guys will be the sole exception. And best of all, the car (E550) runs great!! Blake Eastman They have made a loyal customer out of me. I know I will be brining more ECU’s to Pressertech in the future. Overall, I definitely would rate the service a 10. They sent me three sharp looking decals that now are on my car.
I was so impressed, I asked if I could get some decals of Pressertech that I could display on my car. Results: awesome!, the car performed exactly as they said. The ECU showed up on Tuesday with paperwork and detailed instructions for installation for “first timers”.
Scott did exactly what he said he would do. Scott sent me emails letting me know he had received the ECU, an email when it was in line to get worked on, and he even said they would work on it on Saturday so they could get it in the mail to me by Monday. I was so surprised with the level of service that happened. I didn’t expect it back until sometime the next week knowing it was the weekend. After all of the questions were answered, I sent the ECU overnight on a Friday afternoon. I can honestly say that Scott answered every email within an hr and most of them within minutes. I must have sent him over 10 emails with questions over the next couple of days. Being a novice to tuning an engine by ECU, I had follow up questions for Scott. Scott, with Pressertech responded promptly to my email and answered all of my questions. After I read some of the other reviews for Pressertech, I decided to send them an email with some questions.
