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 is 14.00psi in 4th gear which will taper down by redline. 3rd gear will see around 13.50psi. Air Fuel Ratios should be around 11.0:1 during spool, 10.8:1 in mid, and 10.6-10.8 by redline.


The AEM CAI map may see upwards of 14.5psi in 4th gear and is tuned up to 15.

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.
