    Earlier this month PorscheBoost took a look at the GIAC and Cobb software tuning options for the Macan Turbo 3.6 liter V6 model. The conclusion was that Cobb offered a substantial torque advantage. Well, now PorscheBoost will look at Cobb and GIAC ECU flash software for the Macan GTS and S with the 3.0 twin turbo V6. Let's start with the Macan S which in stock form offers 340 horsepower and 339 lb-ft of torque. GIAC gets a baseline of 266 horsepower and 261 lb-ft of torque on a Mustang dyno: You will notice horsepower increases 301 at the wheels but torque jumps up by 110 lb-ft for a huge gain. Again, the majority of the gain comes down low in the curve which is no surprise. Cobb's curve is similar: The main difference is that Cobb shows they also have 100 octane race gas tuning available. They also top 450 lb-ft of torque at the wheels but once again there is likely a correction factor at play. We wish Cobb just posted uncorrected and raw Mustang dyno graphs with the peak figures as their graphs are not as easy to read or anywhere near as useful. Regardless, here are the gains: MACAN S POWER GAINS Stage 1 91 Peak Gains : +9.43% HP, +21.24% TQ Stage 1 91 Max Gains : +37.30% HP, +37.29% TQ Stage 1 93 Peak Gains : +12.48% HP, +22.38% TQ Stage 1 93 Max Gains : +40.94% HP, +40.94% TQ Stage 1 100 Peak Gains : +14.56% HP, +26.28% TQ Stage 1 100 Max Gains : +41.73% HP, +41.72% TQ Let's take a look at the Macan GTS now which features the same 3.0 liter V6 engine as the S model except in a higher state of tune offering 360 horsepower and 369 lb-ft of torque. The baseline from GIAC shows the GTS is substantially stronger than the S with 302 horsepower and 314 lb-ft of torque at the wheels: The tuned figures are 334 horsepower and 413 lb-ft of torque at all four wheels. More power in tuned form than the S model. This is difficult to explain as the turbos are supposed to be the same between the two models. The GTS has different camshafts though, a revised intake, and stronger pistons. That is likely the reason for more power from a tuned GTS. Now let's look at Cobb's results. Once again, without the peak figures on the graph Cobb's data is not nearly as helpful: Their tuned GTS figures do show greater separation between 91, 93, and 100 octane race than they do on the S. On race gas they are approaching 500 lb-ft of torque at the wheels. MACAN GTS POWER GAINS Stage 1 91 Peak Gains : +5.25% HP, +15.74% TQ Stage 1 91 Max Gains : +34.72% HP, +34.81% TQ Stage 1 93 Peak Gains : +9.26% HP, +19.04% TQ Stage 1 93 Max Gains : +36.31% HP, +36.59% TQ Stage 1 100 Peak Gains : +9.26% HP, +23.86% TQ Stage 1 100 Max Gains : +41.77% HP, +42.07% TQ To summarize this comparison is not perfect as despite both companies utilizing a Mustang dyno Cobb looks to be correcting their figures which show substantially more torque. We much prefer the raw uncorrected graphs that GIAC presents and commend them for doing so. The only way to really see the difference is to put the same car on the same dyno with software from each. In the end, the choice likely will come down to cost, support, and the variety of fuels supported. In these areas, Cobb has GIAC beat especially when you factor in the utility offered by the Accessport.
