We left the Ralliart with
HB Speed to test the new firmware for COBB. Initially there was an issue where Jon could not load the new maps. A day later, COBB sent out a revision and Jon was off and running. Over the next week, HB established stage 1 and 2 base maps for the car.
The graph below represents a the factory tune compared to stage 2. The car was stock with the exception a test pipe (for off road use only). So the gains are about
45 peak WHP and 57 TQ. Not bad for 91 octane and a "stock car" and pretty amazing for just base maps.
EDIT: This tune was done
without a boost pill.
Also, these are the maps that will be available to the public either through COBB, or you can have one tailored to your needs by HB Speed.
