cadillac 4.9L pcm tuning, fastchips/superchips = 20HP & 15lb/ft TQ
I can reprogram the 91-95 deville/fleetwood, and seville/eldorado PCMs. raise rev limit, remove top speed limiter, change shift points, change speedo output based on different tire sizes, lower thermostat temperatures based on a different t-stat being used, eliminate emissions, change idle speed, change idle-down coasting rpm for the ISC motor, etc...
I can also provide the superchips/fastchips fueling and timing tables, which gives you an additonal 20HP & 15 lb/ft of TQ gain to a stock engine
cost of getting this from superchips: $300. my cost to you, $125
that $125 price includes shipping. If anybody is interested, email for details:
