The B48 is rated for 400-450hp so it is a strong engine internally.
That being said, there are some common suggestions for anyone wanting to tune this car - the 'charge pipe' is prone to cracking and should be upgraded. This was easy enough that I was able to perform it myself, but a shop shouldn't charge more than an hour of labor (max) to get it done.

whats point of tuning if you dont go above 4k rpms
Also, charge pipes are a problem on the n20 not the b46. Been running stage 2+ with no charge pipe upgrade or problems.
