I don't think I'm pushing the car to its limits, but I am aware of the risks associated with aftermarket tuning. But I'd like to hear from those who've had MAJOR breakdowns (blown engine, etc.) as a result of a similar setup. Am I being too much of a p**sy? LOL

Any feedback would be appreciated!
You really can't go wrong with your stated N55 mod plans. You'll need NGK 97506 spark plugs gapped down to 0.022". You don't say which Wagner but I highly recommend the Wagner Competition series FMIC because it's quicker flow, less intake pressure drop and less turbo lag- so well worth slightly higher cost. Fabspeed catted downpipe is guaranteed against Check Engine Lights so may want to include that in your models for consideration. Same for charge pipe. I believe that people have had good experiences with VRSF. I've used Evolution Raceworks charge pipe and can verify perfect fitment with the Wagner FMIC.

BootMod3 Stage2 N55 EWG 93 octane is a smooth powerful tune and the included automatic transmission tune is tremendous. I considered a custom tune ($500+) but people I respect advised against it. The OTS tune is powerful and safe. I was told that it would only be worth spending $ on a custom tune if I was installing more exotic fueling and/or a larger turbocharger.

Good luck with your mods!
