Keep in mind Ronney is running Magnaflow Catback exhaust and a "CAI"...
I'll be saving my money until any sort of dyno graphs are produced....

Intitial Stage2 Test Results courtesy of RonneyF over at dodgemagnum.net:Part # Application
90404 2004-2005 Magnum and 300C with V-8 Hemi
90404s 2004-2005 Magnum and 300C with V-8 Hemi using 91 or higher octane + modified exhaust
90405 2004-2005 Magnum and 300 with V-6
90405s 2004-2005 Magnum and 300 with V-6 using 91 or higher octane + modified exhaust
$309.95 for stage 1 $319.95 for stage 2 (s models)
Not very impressive for $300.Test summary (OPINION ONLY). $320 + $30 shipping + 2 hours of my time $480 = $830 of total crap. SAVE YOUR MONEY.
Unless my ECU is in the special classes taking the short Magnum to school, and takes more time than a plug-in to learn the chip, I got negligible differences.
OK - These numbers are based on ESP off, dead stop to WOT (no power braking, shifting, etc. to try to be fair). 2 runs without, 2 runs with chip.
Without chip:
1/4 = 15.00 at 91.1 mph; 0-60 = 6.57
1/4 = 14.85 at 92.3 mph; 0-60 = 6.42
With chip (30 minutes later):
1/4 = 14.8 at 92.4 mph; 0-60 = 6.42
1/4 = 14.72 at 94.2 mph; 0-60 = 6.37
All done at same level blacktop, 46 degrees outside (according to car).
Before trashing the chip too much, I will say that after the battery reconnect, I half-assed the throttle calibration, although it didn't feel too bad from where I had it before the chip install. I'll work on that a little and see if the numbers get better. Also, I'm pending a ticket right now, so I'm trying to keep the potential for another one to a minimum. I'll do a little more testing later. As of now, I'd say save the money and see what else comes out. Maybe it will get quicker as the computer learns??? Hard to tell with only 2 runs.
