Sharing the final set of our tuning results from our custom tuning work with the Vargas Turbocharger Technologies in California. Here’s Tony Vargas’ (owner of VTT) online posting/review of our final results with the second to largest of the turbo options in the VTT kit, twin GTX2863R.
To put these numbers into perspective, with approximately 15-18% drivetrain losses this kit is making 850-885HP at the crank/motor with stock N54 engine internals!
Tony Vargas’ review and comments:
Well, we accomplished what we set out to do. When D and I first started this tuning, he actually threw a number out there and said I think 720 is a good number to shoot for a goal for proof of concept. I agreed and we set out to make it happen. Over the last month or so with a few set backs we got it done. This power was made with very conservative timing and there is MUCH more power to be had with a few taps on the keyboard on D’s end. When we hit 725 today, me the OP, and D all decided we got what we came for and to let the production kits in whose ever hand they may be go about pushing it any further. So the kit will come off this week to start production and I move into the N55 and other things I am working on. Thanks everyone for the continued support. If the other guys comes back with a higher graph, we honestly don’t care. They are now on their 2nd production revision which looks to include a new manifold and a new turbo. If our kit was at that point I would sure hope to be making more than the kit that is in prototype stage and has now seen a dyno 3 times. Big thanks to PTF, COBB, and my brother Dave for the patience. Enjoy the rest of your weekend.

ERC 109 unleaded race gas for an added safety net (obviously we didn’t need the extra octane, as we stopped once we hit our goal)
+meth for cooling, we had plenty of fuel and could have most likely done a pull with it off and netted similar results since we were running 109
