DME report/PPI help
please see attached PPI. DME report included. Has overrevs into ranges 3 and 4 with range 4 having MORE than 3. The guy from the shop said he has never seen this before. Should I worry about this? Owner said he has never tracked the car. No other concerns bout the way the car drives, et. Car is in low 40s for miles with some maintenence that needs attention, 40k service, brakes/rotors/ door panels lifting (is this really a 4700 repair???. ).
this will be my first 911 (2016 GTS 7MT).
Mainly concerned about DME report.
Any advice would be greatly appreciated

Over revs on manual transmissions are not uncommon. How many hours on the car now? Hopefully not 500.
This would be a hard pass for me just based on this report. Others will chime in I’m sure. The potential cost to you in the future to repair the engine could be ginormous.
Best to you.

I wouldn't worry about this issue. Engine is fine.

Over at least 400 hours ago on range 4 (46 times is .383 sec). Do you have a maintenance paper trail?
If well maintained, I’d not worry about the DME range 4. Price for service isn’t surprising, but validates why I do my own

Could someone please explain the "ranges". range 1, 2, 3, 4? Sorry but need to learn something new today and wondering why there are four different ranges? What do they mean?

there are 6 different ranges.
1-2 are hitting the rev limiter on up shifts and not an issue.
3-4 are higher overrevs but if it's been a few hundred hours probably still no big deal.
5-6 are a lot more concerning because they probably indicate a bad downshift.
i don't think porsche will certify a manual with ranges 5-6 but someone will chime in if i'm wrong. there are other threads discussing this.

OP, in your case, I think you are needing to decide if the time spent at those higher engine speeds is worth any 'potential' mechanical issue down the road. As others noted, they took place a long time ago. If you are comfortable with that, the maintenance history of the car, and how it feels/sounds, go for it (but take emotion out of the decision). A good PPI with specific mention of the DME report content would be well worth the cost.

The fact that is a MANUAL, perfect choice! I would never have bought my 2015 GTS if it had a PDK even with the mere 98 miles on it in 2018 when I bought it. BTW, zero over-revs still to this day. The shop should have listed the total running hours.

The torque/power vs. revs. curves for the 3.8 l S /GTS motors published by Porsche Engineering end at 7750 rpm. This clearly is within Range 3. For me it means, no immediate problems up to this limit.
