Just got my whipple 2.9 installed and running last night. I purchased directly from whipple and did the entire install in my garage in about 24hrs spread out over three days. The kit is the best put together kit I have ever seen. Fit and finish is second to none. Packaging was so good it took an hour just to tear all the foam off. Only small complaint is the instructions while very detailed have not been totally vetted for the 2014 srt. Some things were completely different and a few things just not there. They definitely need a revamp for the new SRT. However everything was there and worked with the cutting of a few hoses and swapping one fitting. Also want to give props to Jeff at whipple. He was a big help on the few little issues that came up.

So far it is running like a scalded dog. tranny cant always find a good shift point at partial throttle because the power throws it off a bit. paddle shifting is furious though. I love it. Also wheel spin on either the front pass or rear pass side is spontaneous and could happen at any speed below 60 when you gas it. This is an issue unless you tractions control turned off.

I'm running the same setup in my 2015. It makes 8.5 PSI of boost unless temps get well below 0c...where it will climb to 9 PSI. You have to turn traction control off in Auto mode or wheelspin will close the throttle under WOT, and you do get plenty of wheelspin.

Moving to sport mode rids the issue.

Tranny has some issues in higher gears trying to upshift...

We dialed the timing back and used very mild AFR tuning...and she makes a very safe 580 WHP. She has a good 70 left in her if I want to forge...

I wish. We had to swap out to a 2014...and I have had some issues since.

UConnect handsfree had perfect noise cancellation and outstanding audio quality, but now sucks horribly. I can't understand why this changed, because my impression was that no part of the UConnect has anything to do with the ECU, but obviously, there is a link somewhere.

The tuner built the tune entirely from scratch...which took a few days.

We have to go back and tune more - there is quite a bit of surging and power delivery needs to be evened out, but she delivers a ton of power and kicks like a mule!

Transmission needs some tuning as well...there are issues there too.

Slips into sport mode on its own while it indicates Auto mode on the dial, but Sport mode on the cluster.

They absolutely are! Chrysler is no different than other makers with regards to locking the computers...they're all dicks when it comes to this. That said, this truck lends itself to a blower as if it was supposed to be stock equipment.

Best bang for the buck on any gas vehicle I have seen is a blower, and this one just cries for a PD blower...just because she's AWD and weighs 5300 LBS. PD blowers are perfect for this application! I'd do it all over again. My issues are being fixed one by one and nothing that would make me NOT want to d this all over again. I will probably go for some forged internals next year and just untap what's left in the tuning for the blower; about 80 more HP IMO.

True they don't have a tune, because they haven't been able to unlock the 2015 ECU. We bought a 2014 unlocked and tuned it from scratch on the dyno and in the streets. She's pushing a cool 580 RWHP but dialed down from over 650 or so. Aside from the stupid transmission (WOT) shift issues (due to increased power), she runs perfectly.

I don't use canned tunes on gassers. I always dial it in on the dyno.

I made the decision to go with some forged pistons and rods, which I'll do late summer when I have time, and unleash the rest of the power left in there.
