Welcome!

It's unfortunate that your N55 engine was the one had to be replaced. The bearing issues impacted a small percentage of 2012-2013 N55 engines.

The good news: the new engine of course.

Nice to see OEM charge pipe being replaced. Is it comparable to Evolution Racewerks?

Looking forward to future updates.

The evolution definitely look more impressive than the cts.

Does anyone think the above mods will get me to 425whp on regular gas (93 octane)?

I believe you can, if you want easier gains though drop the JB4 and get a tune custom for your car. I believe this will maximize your gains since the tune is optimized for your car + mods

Since it will be a daily driver when I move to Mexico (they said all this might make the car illegal for US streets ;-), I like I can tune it down for daily driving but can re-tune for track from sitting behind the wheel. Make sense?

Get a flash tune, it is 100X better than any piggyback for all use cases including dailying. Use your right foot to "detune".

Thx, will look into it.

Does anybody think I should change the planned PURE stage 1 to a PURE Stage 2? I would not change anything else. Thx
