Clay,
The answer is a resounding yes!
Without changing your tune your Omni will make more horsepower. The denser and colder air charge alone will reap HP improvements.
Now consider this too, either your have decided on an ceiling for your boost and/or timing on your tune. With the injection your threshhold for boost and timing has jumped significantly. The superior heat absorbsion of the water mixed with the high octane of the methonal creates combustion which is virtually detonation free. Our buddy the
knock sensor will be bored waiting for something to report to the ECU. The ECU loves to show off it's timing table and will on it's own increase your timing levels w/o you touching the distributor yet.
Then pull out a 1/2 point of AFR to the low 12's high 11's watch the mph go up again. Grab a wrench loosen that dist lock nut and dial in a degree or 2 of timing.
Got a Cal with built in knock detection? Tune this thing so simply but safely that you will be laughing all the way.
You say well I have to feed this what will that cost me? Well I buy my Meth here locally from a Sunoco fuel Distributor for 2.40 a gallon. Cut that with 50% water and for 1.25 a gallon you have a race gas cruiser. Or out of the area, just get a jug of -20 deg washer fluid, add a bottle of Yellow Heet and your off and running again.
I have made many boosted Dodge owners believers and very happy with thier decision. Without advertising anything but real world results. I and others have the dyno's to back it all up, the ET's/MPH and the wins.
It's time to "Chemically Intercool"
