I'm considering getting a stage 4 kit on my 17 SG, can anyone give me the heads up on whether its worth the coin? Pros and cons?
Thanks in advance

Just my humble opinion after riding and dyno testing a stage IV 114. The 515 cam ruins everything. Absolutely slaughters the low end power. Just the 117 kit and the 447 cam would be
way better for Touring. The 447 is the only one that doesn't loose low end power. If you could get the Stage IV kit with the 447 instead of the 515, you would have a very fun ride. Not sure if they can tune that one with inside the EPA window? If warranty was of no concern. The best bang for the buck is a 124" Piston kit from
Suburban Speed ,
TTS 200 cam and a
TTS Tuner, stock heads, stock TB. 120hp/130+tq. Call it a day.
