Makes you wonder if indeed works or not, yet TE does NOT have a JBD or Even any Flash just meth as far as i am concerned.
Trust me, i do understand what you imply and it is well reasoned to be a bit skeptical of ANY product w/o R&D, that is why I called RENNtech into this to do investigation with WAGNER and also with ECOTUNE. But, if no one party participates then we are ALL SOL!!
Axel, I cannot speak to TurboEddie's experience with his CX Racing IC (I've read his posts though), but we are talking about two very different IC's. I do recall him complaining initially of some extra turbo lag - a possible negative side effect of an improperly sized IC. That said, I believe TurboEddie is also running his own personally designed/built piggy-back tune, but there is no way (that I am aware of) that a piggy-back can be adapted to account for an upgraded IC. Our DME's are very smart and tend to adapt well to keep systems in check/at factory tolerances unless tuned otherwise at which point a properly sized/functioning IC could prove to be a benefit.
What would be interesting to see if you or someone local to Renntech can get your hands on a Wagner IC and hand it over to Renntech for some testing/tuning to see if in fact there is anything to be gained w/a Wagner IC.
I don't mean to be a Debbie Downer here, just trying to be practical about it. I want performance options as much as anyone, which is why I am a litte (actually a lot) disappointed Wagner has not done any testing yet and to take it a step further actually performed some data logging and back-to-back dyno runs and compare it against stock. Shoot I would be happy if it proved to just significantly lower EGT's under all load conditions.
