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.

Specs:
Full Pro tune done by the guys at Pro Tuning Freaks, using the COBB flash tuning system
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
Smoothing in both 0-5

We’re pleased to share another great review from Derek (@redlineryder), a recent tuning customer of ours. Thanks Derek for sharing your experience and best of luck with your N54 ;)

My car before the install was 100% stock with a Cobb PTF 94 octane tune. I’m still under extended warranty so this setup was perfect and made good power. It’s crazy how just changing the software can wake this car up. However, like so many of you already know, it’s never enough and I wanted more.

I didn’t want to install catless downpipes or an aftermarket intercooler because of possible hassle from the dealer, I figure they will see removing of emissions equipment worse than some funny lines going into the charge pipe

I ordered the following:
– Aquamist HFS-4
– Howerton Engineering 2.2 gal. tank enclosure
– (2) Aquamist adapters for silicone/rubber hose
– HP Autowerks silicone meth elbow
– BMS DCI

ProTUNING Freaks are local to me and were nice enough to tackle the lengthy install. I wanted the install to be clean and PTF kept me updated throughout the day. I dropped the car off early Saturday morning and came by early evening to see it finished. We hit the road for some tuning afterwards. It was a long day and I appreciate the work they did, it turned out great.

I haven’t had a chance to dyno it yet since I’m on snow tires but plan to see what it puts down once the summers are on. I can say that the meth + DCI has smoothed out the power band and now it pulls well past 5,000 rpm whereas before it felt like it was falling flat on it’s face, it also sounds alot better with the added timing

I’ve had the setup running for just over a month now and wanted to wait before doing a review. No regrets, the install is clean and runs flawlessly. The failsafe is cool and turning the gauge off acts like a quick valet mode. I also ordered some black wire cover to put over the meth lines in the engine bay to make it look cleaner.

Disregard the grim in the pictures, we Canadians are subjected to alot of $#@! on our roads.
