So I just got tuned by Cobb Tuning Plano and the results are staggering! The initial plan was to install a GrimmSpeed 3port and a Synapse Synchronic BOV. Due to some unforeseen issues getting the Synchronic installed, Kracka and myself said screw it and just left the stocker on. After that, we drove over to Cobb (staying out of boost) and then let Calvin work his magic. All I can say is that guy knows exactly what he is doing as you'll see by my results.
So part of the process in doing everything in the order I did was to see how Cobb's OTS maps compare to their protunes. I'd have to say the OTS maps are pretty conservative but give the user enough to be happy with. Here is a break down of how my tunes went along with the mods at the time:
AMS FMIC, UICP, Intake
HKS catback
Results:
Stage1 AMS OTS 93oct: 305hp 291tq 20.6psi
Once I got protuned:
Stage1 AMS 93oct Protune: 317hp 322tq 24.5psi
My next step was to throw a test pipe on there and flash to Stage2. I also changed out my catback and went with the Specialty-X because I REALLY like the design and it looks just so nice. This was perfect as I used the NTEC Dyno Day to see what the Stage2 map would look like. I ran into an issue getting the stock cat off so Cobb was very generous and swapped out my cat for the testpipe at their facility. Calvin said that it might overboost with the testpipe even on a Stage2 map, so I decided to run the car with the Lowered Wastegate map just to be on the safe side. So here's the full mod list and results for THAT dyno run:
AMS FMIC, UICP, Intake
Specialty-X catback
Megan testpipe
Results:
Cobb Stg2 AMS 93 OTS LWG: 315hp 323tq 23psi
Kind of disappointing that it came out practically the same as the Stage1 protune but I expected that with the OTS maps having to be conservative so that they work for everyone.
So this brings us to today. There were a couple more changes to the setup but the only real key change was the GrimmSpeed 3port. The other addition was an AMS LICP, which has been said to not provide any gains. So why get the LICP...well I plan to get my piping powdercoated so I want to do the whole set. So once again, here is the full mod list for today with the results:
AMS FMIC, UICP, LICP, Intake
Megan testpipe
Specialty-X catback
GrimmSpeed 3port
Results:
Cobb Stage2 93oct Protune: 343hp 358tq 26psi
I am extremely happy with the results. I didn't know how much I'd make, but I was thinking around 330hp/340tq. As you can see, I made quite a bit more. My goal from the beginning of my mod process was to end up at around 330whp....my goal has been met!
I would just like to thank all the staff at Cobb Tuning Plano for their continued awesome customer service and expertise, especially Calvin. He's the one doing all the magic on the dyno. Thanks also go out to Kracka who's helped me along the way both with discussing things/issues and for lending a helping hand. {thumbup} to everyone!
