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 17.0psi in 4th gear which will taper down by redline. 3rd gear will see around 16.50psi. 5th and 6th may see closer to 18psi which is perfectly normal. Air Fuel Ratios should be around 11.4:1 during spool, 11.0:1 in mid, and 10.6-10.8 by redline. I highly recommend monitoring the Air Fuel Ratio with a wideband o2 sensor such as the AEM Uego, or the Innovate LC-1 if available.
