Additional Information


Further instructions will be provided upon receipt of your new map. This will include details and proper map break-in procedures/tips. Target Boost on both maps is 16.5psi in 3rd gear which will taper down to around 14.5psi by redline. 4th and 5th gear may see up to 18psi. Air Fuel Ratios should be around 11.5:1 during spool, 11:1 in mid, and 10.6-10.8 by redline.

This map was originally designed for 93oct gas but can run on 91oct as well (RON+MON/2). It has been properly detuned to allow variances in octane down to 91 with optimal performance. While minute gains can be achieved through additional fuel reduction, it was found to be negligible to create a separate 93oct map.
