We have had 6 SRT's installed and put through our dyno with very similar results. The one thing we find odd is the way the vehicle configures itself for a HP testing. We have not nailed down why some vehicles elect to test AWD and some elect to test RWD. The one thing is sure they seem to have a mind of their own. In each case we followed the exact same procedure for testing. Pulling fuses and using the Diablo to over-ride the traction control. We have reported it to Diablo and will continue to work with this on the subject.
The hardware, power levels and install instructions are what we consider done. The latest 2 we did have headers and exhaust... A 2012 produced 561-RWHP AT 5.5PSI cleanly and drives wonderfully.
We are nailing down the 5.7 Durango next, it has required considerably more work than the SRT to tame. It has nothing to do with the hardware, its virtually the same as the SRT, it has to do with the OEM programming and how inconsistent it actually - there are OEM flaws that are amplified when SC'd.
You can choose to wait - or you can choose to go your own route. We ask that company invest it's itme into the product as well and reported the information over the last six months, this too is work. We try to avoid all questionable's with regard to hardware, install and tune before we go 100% retail. We are currently in a soft launch if you want to be part of the soft launch and/or want to order a pre-production kit, call in or email in and we'll invoice you out and get a kit out to you for testing.
We know there are many FI options popping up our goal and objective is the be the go-to kit and the one that sets the bar
