DA = 900 - 1100 ft
2010 Touring 7AT
Mods are:
Empty trunk - 3450 lbs with 250 lb driver
Enkei 18 x 10.5 rear wheels w/ MT ET Str SS 285 tires @ 23 psi
MT skinny fronts on 18” factory spare wheels
Stillen G3 Intake
48 row cooler (ET penalty due to weight)
Mobile 1 10-30w oil
DIY ported upper and lower intake
Motordyne ART pipes
Ackrapovic CBE
No yaw or traction control
10 gal E85
GTR Injectors
Ecutec tune
3.69 Gear w/VLSD
Odessey 680 battery
Synolimit TBs
Z1 2 pc front rotors
Car runs good, but it is maxed out and is going about as fast as it can with the power available. Happy with the 12.89 but feel like the Ackrapovic exhaust may be holding it back? Scratching my head on what to do next...any suggestions are welcome.

Hmm IDK man we have very similar mods so you should be close to what I run. Only thing I can think of is you need better weather. I was running 12.6@111 in 900 DA this summer. I ran 12.45@113 yesterday in -700 DA. We are both on E85 and I think the biggest differences are that I'm on UPREV, have long tube headers and im on stock gears. Are you dyno tuned or street tuned?
