Liza & most of the time Vince is amazing...lol. Nah, kidding, these guys are awesome folks to deal with. I purchased their Stage 2 turbo, turbo inlet, intercooler, engine tune, and high pressure fuel pump for my 2018 2.5L Boxster GTS and they're products and service have been top notch throughout the entire process. And, most importantly, the difference in how the car feels is nothing short of amazing. Even before we actually tuned it for the new mods and just had the stock OTS Cobb tune still loaded, the Thomas Tuning and Performance's tech that did the install was blown away with how the car felt compared to the previous OTS Cobb tune and exhaust. Then, after getting it tuned by Sam by Design through Raggdoll, you can't even imagine the difference. How does over 500 ft. lbs. of torque sound? The Cobb datalogger is showing 544.3 ft. lbs. of torque at the pdk, so it should be pretty dang close to that on the dyno. OTS Cobb tune was 375.2 ft. lbs. of torque. No tune and exhaust was 353.5 ft. lbs on the actual dyno. I'm going to take back to the same dyno next week, so stay tuned...this thing is a beast. We'll probably do one or two more final tunes on the dyno and I'm guessing we'll be north of 400whp and north of 500 ft. lbs. of torque on 93 octane pump fuel. These cars with their mods are simply amazing, to say the least. My record run through the Tail of the Dragon in East TN is 1.57g in a turn...not on a track. Can't wait to get it fully dialed in...it's an awesome sleeper. Big thanks to Liza and Vince for helping convince me to go with Stage 2...no noticeable difference in lag compared to stock when running in Sport and Sport+ modes. There might be a tad more lag when running in whatever they call the normal mode on the Sport Chrono packages, but I never run in that setting anyways...boring! I can pull away from much higher cost vehicles now with ease...just brings smiles from ear to ear. Worth every penny...more smiles/mile right!?!?

I'm glad I came across RMS on the 718 forum. I wanted more performance out of my Porsche Cayman and they are the best company for upgrades on this platform. Their rennen turbo upgrade really transformed the power of my car for less money than I spent on expensive downpipe upgrades from other companies that didn't do much for my car... My tuning shop tech who installed the turbo was also very impressed by how the car felt after the upgrade. If you want more power for your 718 car, this is the place to contact!

I purchased the Raggdoll Series One turbocharger upgrade and the turbo inlet upgrade from RMS for my Porsche 718 Cayman GTS and was very pleased with both the products and the customer service from RMS! Everything was high quality, packaged nicely, and produced wonderful gains in both power and driving experience. RMS was there along every step of the way to answer questions and provide any necessary customer support services. I'll be adding their HPFP upgrade next, and I'm excited for what's next to come!

I purchased a RENNEN turbocharger for my 718 T. I had a special request, which was to get the turbine housing coated with Swain Tech white lightning thermal barrier coating and RaggDoll accommodated without hesitation even though it was something new for their team. And then, even though my car is a 2023, it had a newer revision turbo on it which I assume is used on the 2024s. The team at RaggDoll was able to expedite the reworking of my turbo to minimize the downtime. As for the turbo itself, where the stock turbo falls flat on its face after 6500rpm, the RENNEN keeps torque flat all the way to 7500rpm redline.

Raggdoll Motorsports set up two dyno sessions for my Porsche Turbo S. The Porsche touts a 4.0-liter built engine and head work facilitated by Sam at ByDesign. Also has the XR ByDesign turbo kit with all the supporting mods. The first session the PDK kept transitioning out of manual mode. During the second session a boost leak at the throttle body boot ended the session early. We managed 812 hp on a Mustang dyno at only 20 psi of boost. The Porsche should be building up to 33 psi. Looking forward to hitting that +1000 hp next time! Check out RaggDoll Motorsports for Porsche parts for the Porsche 718 platform and for dyno tuning. Sam at ByDesign has you covered for all your Porsche 911 parts and tuning. And thanks to @kyletunedit for letting us use your dyno.
