I’m not a big fan of the Pzeros. Just not as confident with themI increasingly only use the Cobb stage 1 (370bhp) in my 718 CS or even stock map in inclement weather, even though I’ve a custom tune (390 bhp). The issue is any more power than Cobb s1 and it’s hard to put down- accelerate hard and I get wheelspin, PSM light and if it’s slippery some back end fishtailing. It’s not a problem in that PSM sorts it out and avoided by being more gentle with throttle but it raises the question of what’s the point in having more power if you can’t readily deploy it.
The 911s I’ve driven don’t seem to have this issue, I guess due to more weight over the rear axle.
I don’t know the best solution. I’m considering changing Pzero N1s to Michelin PS4S (although no N rated in 19” in the UK) which might be stickier, or getting a CGTS- although unsure if that’d be any better (PTV perhaps). Maybe a heavy suitcase in the rear boot would help! Anyone else experience similar with power increases? Cheers
The only tuner I know offering a tune for GPF equipped 718’s is FVD Brombacher.Thanks for your suggestions. I think I‘ll will go with tyre change.
On another note, does anyone know if the Cobb maps work with GPF equipped 718s, in the UK this is post September 2018 models
I just got a Cobb with the 10% sale on thanksgiving....hoping to use that 10% towards a custom tune!I think COBB really failed in their marketing for the Porsche products. Most folks have no idea what the potential advantages of the AccessPort over a canned tune are.
Even if you aren't custom tuning the logging is a great feature for gathering data at track days, etc..
I'll talk to COBB and see if they'll split the cost with us..
There is a dyno chart in this thread:I just got a Cobb with the 10% sale on thanksgiving....hoping to use that 10% towards a custom tune!
Do you have before and after a on a custom tune for a stock GTS?

Yeah looking at that and also tracking the APR page, seems like Cobb base tune leaves alot on the table.There is a dyno chart in this thread:
Nope, go near wot and release the throttle. The boost goes to zero and after a sec it jumps up and stays there for a sec or two. Perfect for going out of corners or doing 100-200 I'm not quite understanding what you mean. go near WOT and then release the throttle - do you mean get off the...www.718forum.com
It seems to be for a GTS on 91 fuel and has a dyno chart with stock, Cobb OTS and EQT Stage 1 tune. Results for the EQT tune look great and should be similar to the the APR tune. But the OTS Cobb map looks pretty ordinary with a very mild improvement IMHO.
Just clarifying that the turbo intercooling on the GTS is identical to every other model, but it has a 3rd radiator which is for engine coolant cooling. As fas as I know this only makes a difference at the track. I have yet to see anyone experiencing cooling issues in road driving.... so definately worth having if tracking. If it did have better turbo intercooling, that would be fantastic as a source of extra power.Plus has 3rd inter-cooler so shouldn't overheat or limp etc.
Just received Ed’s stage 2 tune.We've been having some great results with custom tuning via Cobb. Especially impressive with ethanol mixes!
