DHP 1.0 PCM Upgrade

On 12/9/2003, I took 30 minutes and installed a reprogrammed PCM by DHP (Digital HorsePower).  With the modifications that I have, the PCM can be retuned to get the maximum gains from the mods.  You can either send in your stock (or get a cheap spare!) PCM to get reprogrammed or you can have DHP send you another PCM and charge you a Core fee that will be refunded when the stock PCM is returned.  I opted for the latter so that I could get it quicker!  Anyway, here's a list of features or enhancements that a DHP 1.0 PCM adds.

• Speed limiter removed
• 3-1 and 4-2 skip shifts
• Transmission line pressure increased
• Shift points moved (5800-6000rpms)
• Fan turn on points altered
• MAF calibration adjusted for proper year
• Fuel/spark adjustments as follows: Enriches fuel delivery for critical problem areas, Provides a consistent power gain across the entire power band, Reduces spark retard (knock retard), Removes "40MPH WOT lag"

All of these enhancements are only active when Performance Shift is turned on which is nice.
