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 18.5psi in 3rd gear; it will taper down to around 14psi by redline. Boost may be higher in 4th and 5th gear but should stay under 20psi. I strongly urge you not to floor the car in 4th or 5th gear under 2800rpm unless absolutely necessary. Air Fuel Ratios should be around 11.5:1 during spool, 11.0:1 in mid, and 10.6-10.8 by redline on both maps. 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.
