Let us know what you think of your tune

I would be very interested in feedback on this subject also along with some independent RWHP and RWTQ #s. Cobb's website is claiming 30+ % gains which is in the neighborhood of 100 square. That is one hell of a lot on a motor rated a 370 HP.

I got +70hp gain on some of my older 2.2L 20 valve 5 cylinder Audi S4-6s. Thats why I was interested in this.

Year back I had a Focus ST as a daily driver when I worked and with a Cobb tune it hauled *** and after the tune the change was very noticeable, which is not what I am experiencing now on my GTS with the Stage 1 Map - might be time for the Stage 2 sooner than later.

I might just add the sprint booster to this car for $299 and for go the tune until more info is out on this

I had a tune on my previous car and I remember that the ECU had to adapt to the remap. It took about 50 miles or so from my experience. Maybe give it a few more miles? Just my 2 cents.

If you do go Sprint Booster, post your thoughts on this.

B Russ

I can tell you the sprint booster really woke up my 2014 Panamera 4S 3.0tt and its a beast in my 18 Panamera turbo. Seems like No one on here has used them on 991s which is surprising.

Just a side note, when you flash/alter parameters the adaptations are also reset and need to relearn...also apply's to piggyback tunes.

Give it 100 miles or so of aggressive driving to properly get the car to learn the values.

B Russ

You think Cobb would telling people this

Aatish

I mean, I kinda get why they don't tell people to drive aggressively after tune to set...liability lol.
But yea, something about needing to relearn would be nice.

If I notice anything after a few more miles I will let everyone know and if not, I will be change the map to Stage 2 in about 500 miles.

Not sure I would expect to feel much difference on a GTS with COBB stage 1 unless using 93 octane. Here is their graph:



Stage 2 seems to make a bigger difference:

All I use is Shell VPower 93.

Can't speak to Cobb/Flash tune myself....

With my JB4, I noticed a noticeable increase in power after about 125 miles of commuting to and from work (roughly 2 days).

A good friend had his car flashed with GIAC. He did dragy tests (0-60, 60-90) right after the initial flash, and then every day after. Significant improvements from "fresh" pulls to the 3rd day; think it was like .3s for the 0-60 and nearly .5s for the 60-90.
For reference, the car had better performance with the fresh flash than stock; so the flash did make an immediate difference. It became better as the car was driven.
