Well worth it IMO and a bargain compared to Audi DSG tuning

Something else I appreciate is the slip from a stop is eliminated so that as soon as you accelerate it grabs, whereas stock would be lazy to engage unless punching it in sport +
PDK tuning also enables the stock clutches to hold more power when set to that map, but that is not a benefit for everyone.
Thank you. This is the kind of stuff I have been looking for...

Gotta say Sam is still the real deal. Contacted him yesterday and within minutes received another great deal. Still the best source there is.
Thanks again Sam

Iím assuming the deal was on pdk tuning? So what are your initial thoughts?

So I finally decided it was time for me to check it out for myself... For the record Iím a big COBB fan and have had APís on my last two cars over the last 8 years. I have a turbo S with 21K miles and Iím running an ots stage 3 tune.

Install: I followed the directions and had a communication issue. (Iíve had over 10 protunes on my previous car and never had this issue) Iím not sure what the problem was but it worked the second time. Initially it said it was successful but the car wouldnít go into gear. Meaning the shifter moved but the car didnít. (And yes, this was after the relearn)

Result: I chose the aggressive pdk tune. The car in normal mode shifted much better. (Unfortunately this did nothing for me as I only drove in sport mode) But normal mode shifted how it should have from the factory imho. In sport mode it was jerky. It downshifted and actually jerked/bounced. It didnít feel right to me. Also the car shifts at a higher rpm, even in normal driving. So I find I have to switch back to normal mode while on the same drive. (Which I donít like) I would try the sport pdk tune but I have read the turbo S guys donít see a difference between that and the stock turbo pdk tune.

So my review would fall under the negative catagory. I plan on changing the fluids/filter to see if it helps. For those considering this tune, I would get that done first. (Itís not cheap) Iím hoping this review helps. Iím a little disappointed COBB didnít offer all the improvements they did with the 991 pdk tune...

I appreciate the reply.
Wondering though, how the "less aggressive" setting would be?

I know the aggressive setting is for "Racing" and / or "Drag racing", as it ups the clamp force (whatever terms can be used for the PDK clutches).
Where as the "sport" or less aggressive setting maybe be better for daily / yet spirited driving.

Anyway, I appreciate the post. I'll take it all into consideration, as I'm still waiting on a few things prior to spending for tuning.


Anybody else??

Unfortunately, if you donít do it you will always wonder. By the difference I felt between the factory turbo S sport pdk tune, compared to the aggressive pdk Cobb tune... Its unlikely there will be any middle ground. Yes, the aggressive tune shifts faster. But itís not a big enough difference to have an inbetween tune. I know three other turbo S owners that tried it and could not tell a difference between the two. For the regular turbo owners the outcome is better, because they come with a slower pdk tune from the factory.

I will get the fluids changed and see if that helps. For the record, my car never had any issues shifting before. My hope was only to make it shift faster, if that was even possible. Of course without the bump/shake/jerk that I have now.

Keep us posted on the Fluid / PDK Service and results.

I'm thinking I'll have it done Also, especially if / when I buy tuning. I just want everything perfect and ready when I add tuning.

Bumping this to see if there's any new opinions out there on the PDK tuning and how well it works.

Just got my Cobb AP and am looking at buying the PDK tuning today or at least by Monday.

Well i got to drive my car today with the PDK "Sport" tune. I Really like the shift strategy of it!! Even seemed a bit smoother as well.

After driving it a bit and getting it up to temp, I did the "Relearn" procedure. Interesting things the car does (sounds, raised rpm's, clunks, etc.) while doing it though.

The drive afterwards seems bit "rougher" at first. Seems like after I put a few miles on it in "sport mode" and in "normal" mode, that it smoothed out a bit. I'm sure since the tolerances were adjusted (tightening things up a bit), that it'll take some time to learn and get completely adjusted.

Secondly, I tried the COBB Stg. 3 - 93 Octane tune.... My car instantly did not like it. Seemed rough and missing a bit. I guess the 3 bar MAP sensors are a MUST for this tune. I immediately switched back to the Stage 2 - 93 Octane OTS tune. MUCH smoother and better running.

I still need to get more miles on it with the tune and PDK tune to get a full review of it, but I'd say buying the PDK tune from SambyDesign was a good move. Now I know why he told me to try the "sport" pdk tune first. The "Aggressive" pdk mode is supposed to hold the gears even longer in each gear. I think that'd be bit too much RPM in each gear for street driving ( Like driving around in Sport Plus was on stock software).
