We also test on street and track. I was personally testing two Stage 1 tunes on Saturday at the track with the Carrera T, datalogging to gather some additional insights. We also do a lot of custom tuning behind the scenes with various tuners so we have a wealth of experience that we hope to provide insights with.

We post as much information as we can but we've never aimed to pit any vendor against each other. We have a great respect for the vendors we offer and we vet vendors with rigor. We simply look for the best overall solution and value. This is why we have continued to recommend M-Engineering tunes due to deep research, development and experience coupled with performance and features. Let me stress, that people have their own unique requirements which is why we also don't rubber stamp a vendor because a particular solution might be better for one person over another. There are some simple things but we always welcome the opportunity to work one on one with folks to make sure they are focused on the right solution for them.

I've never seen a need to get into threads like these but since we were named I wanted to add some perspective. The client purchased and used the ME OTS map for over 2.5 months before upgrading turbos. We provide a free upgrade service on the tune when you purchase the GTS turbos through us. We provided a credit back to help offset some cost to the client as he was frustrated and wanted to use a different tuner. Obviously, we can't refund the full amount of something that was used without issues. It's a tough place but we thought the act of goodwill would help the client, not bring us into a thread like this. I'm glad things got sorted for the client and we're sorry things didn't work out regarding the 2nd ME tune. I can promise you that we continue to test, learn and develop on the 992 platform. We also take great pride in serving Porsche enthusiasts. Many folks who have worked with us understand this, we regret to see situations like this and we try our best to help. All the best, enjoy your driving!

- Jon

So, his concern is more about the latter suggestion (point to something else in the car) vs getting the tune right. At least that is how I understand it.

I talked to the lead tech at my local dealer about replacing injectors and he was skeptical. His skepticism was supported by the fact that the misfire faults occurred on cylinders 2,3,4 and 5 with each one occurring at different times/maps between loading the base GTS map and the last revision I received. The last communication I received from MEng was that if the "next" revision (which they never sent) didn't fix the issue, that I should run a Map 0 to see if the problem went away. They never sent the next revision even though I sent more datalogs. I did say I did not want to replace the injectors so I guess they gave up - don't know. Anyway, I removed the M-Tuner, the stutter/misfires went away i.e., the car ran fine with the stock tune. At that point, I decided to cut my losses and try Softronic.

And if the goal of the OP is to air the facts, then we should disclose all the true facts and let the consumers decide. As we have now flushed out, apparently there is a factual discrepancy on the performance of the ME tune before the turbo upgrade. Not dispositive…..but relevant facts all the same.

Based on feedback from Softronic that the stock tune would be ok, I removed the MTuner and the issue disappeared. This plus the movement of the misfire to different cylinders at different times, made me believe that the issue was tune related not injectors. I was totally convinced of this after I loaded the Softronic tune and had zero problems.

Did you tell them of your finding and how was their response then? btw, I personally think its gutsy to run upgraded turbo's w/o a tune...but I guess its okay as long as you don't stress it. But you also mentioned the misfires and such happen at higher RPM and I assume the ME tune run okay at low loads so running upgraded turbo's with no tune at low loads is a bit of a false negative to me to start with.
