Conditions and octane play a huge role in numbers, fuel has been getting considerably worse over the years in CA with ACN91.

Add some more octane and you'll definitely see improvements, or go for the gusto and look into an E85-based tune once you get supporting mods.

I'm getting ready to pull the trigger and this will be my first mod. How close is the ACN91 map to the GTS? Power wise they sound similar but how is the power delivery.

Stage 1 will make more power than the GTS map.

GTS map is included with the BM3 license, you can try both to see which you like.

I have flashed CS (NOT CS+), GTS and Stage 1 ACN 91. These are my impressions:

CS: It feels like a ZCP car with extra mid-range torque. The top-end performance leaves a bit to be desired, but its a good map to use on the track because of the linear power delivery. It feels very smooth and controlled. It is a good map for use on street tires (think PS4S).

GTS: It feels like the CS map but it is a step-up in power with similar torque as the CS map. This map has noticeably stronger top-end power. It is still very linear and is similar to the CS map in that regard. If I had to pick, I'd run the GTS map over the CS map. I don't have a problem with traction on this map even in 2nd gear since the weather is warm and I am running Cup 2 tires.

ACN 91 Stage 1 - This map is the kick in the face after 3000 rpm. There is a giant torque increase between 3k and 5.5k and it feels like you are launching from a roller coaster from a stand still. You definitely feel the top-end power drop off quickly after 5.5k because of the ACN 91 fuel and the turbos running out of breath at the top-end. This is a fun map on the street if you like hooning around and aggressively passing cars. I wouldn't want to run this map on the track however.
