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.
