It is on par with all other kits in terms of power with similar sized turbo and fueling. Spool will always be an issue when going to bigger sized turbos like this. We are using a bigger exhaust housing AR than most would consider but it is not too large.
Low end torque is great and starts off about 1k rpm sooner than other kits with similar sized turbo. Spool can be maximized with better exhaust as well. Here is the log from the dyno run, 5th gear.

Yes, the head flange is two pieces. The separated manifold makes for a very easy install. We installed the turbo kit on the car with all suspension and subframe bolted up. The manifold was easy install from the top of the car, took us 2 hours to install the full kit with only a jack.
We made this easier for people that like to DIY, and do not have a lift. This kit can be installed at home in a garage, with an experienced mechanic of course.
Boost control has not been an issue at all, wastegate priority is very high as it is in the line of flow after all the merges. It looks a little off due to the tight spacing and o2 sensor placement. We have not had any issues with o2 sensor burning, nor tuning and boosting.
First day off the lot with e40 mix testing:

We understand your point of view fully. We wanted to show you what this kit can make with the least amount of modifications possible on a stock-like car. Making more power is not the hard part. Ensuring the product works flawlessly is more important to us than power.
We offer lifetime warranty on all fabricated parts, (Manifold, Downpipe etc.) and use the highest quality parts and material on the market. Nothing on this kit is shortcut or rushed and includes all parts needed to make your n54 into a monster.
Clutch and meth kit will be here soon for more testing. We have a beta tester coming in a couple weeks ready for 700whp+ setup. More info on that will be released when the time is appropriate.
