Hello all!
I have a 2012 2SS/RS convertible Camaro A6 with Twin Turbos and just got my MPVi3, starting to learn what it can do.
The car has been tuned twice that I know of. The first time was over 8 years ago when the engine was modified with a cam and stall. The second time was around 5 years ago when the turbos were added. Recently, I updated the differential with 3.91 gears and needed to change the gear ratio for the speedometer. So, I decided to learn how to do this myself.
I used the Gear/Tire wizard, and everything worked great. The speedometer is now working correctly, and it feels like the shifts are better now that the transmission multiplier is set correctly.
The engine has undergone several modifications, including:
2 x Borg Warner S300 60mm turbos
ICT Billet High Rise Manifold
FI Cam 231/239 #50 .617/.624 115 LSA
BTR Dual Spring .660" & Trunnion kit
LS3 upgrade, LS7 Lifter set
Katech C5R timing chain
Meling Oil pump / PATC Billet Converter
Fast 85lb LS3 injectors / ZL1 fuel pump
3.91 Rear Gears / Detroit TrueTrac Diff
The last tune when the twin turbos were fabricated and was on dyno but tuner was remote, and honestly the car was not ready for it. I was told the AC was stuck on (custom dash kit locked up) easy reset but they never asked. Also, I found the exhaust manifold bolts were only hand-tight, which likely let in some air. The gaskets blew a week after I got it, and I discovered this and some other questionable things. I won't go into details.
The car runs okay and has been ok for years, but I don't really push it. It's more for looks than power, but I know it can be so much more!!!
I understand it's going to take some time to learn all this through trial and error. I've been learning when I can from the web, posts, videos, and more videos.
I just wanted to post my tune status and see if anyone who knows anything can spot anything that stands out that I should look next?
What I've changed so far in this tune: ( Compaired to 2 stock ones so i can see what was done in past)
Update 1.00 Speedo Calibration Tire Size: 27.79 28.7 Gear Ratio 3.27 3.91 Trans Multiplier 0.864
I spent alot of time making this setup look like it does. i did everything but the welding stuff and pin striping
