I just placed my order for a single tune and TCM tune. This was my first tuner I have ever placed. I made some mistakes on my original order and sent a email asking questions Justin Granger took very good care of me. If this is the type of support PPEI gives there customers I will be ordering all my tunes from them with upgrades to my truck. Justin went way above any customer service I have ever had with a order I’ve done online.
After being on the fence about buying tunes that are emission compliant. I finally pulled the trigger on the 80hp single tune for the ECM and TCM tuning. The support PPEI provides to both customers and potential customers is top notch. I created a ticket to ask questions, and Chad Cole helped me find the best tunes for my needs. I couldn’t be more happy with the performance of my LML with almost 15% gains across the board.
Whether you’re at the track or on the road, your stock ECM and TCM, IMO, are not efficiently working together. After flashing PPEI’s ECM and TCM tuning for my stock 2015 LML and 2019 Powerstroke, I learned quick at the extreme differences the tuning provided. The engine runs smoother, works less, and is more fuel efficient. The TCM tuning allows your transmission to efficiently convert the power through your drivetrain with spot on shift points and extremely firm shifts without any signs of trans clutch slippage. I worked with a couple technicians at PPEI through email and revised an original PPEI TCM file and made it what I thought it should be. After a couple months of fine tuning, I now believe PPEI has the most highest quality TCM file available for the LML TCMs. If you’re not running PPEI tuning regardless of vehicle manufacturer…. You’re missing out!!
The EzLynk is hands down one of the best devices ever made in the diesel performance industry. Paired with PPEI it's even better! This is our go to at Lead Foot Diesel Performance. Keep up the great work guys!
