Have a Honker CAI. No problems before the Predator tune. No problems after it either. SOTP - Vette seems to pull harder with much crisper throttle response. IMO- worth it.
I bought a K&N...no tune no ses or anything...just slap it on in 15 minutes and go.
I open up the shroud to get cooler air flowing in there and it certainly seems like a SOTP gain, but I havent been back out to the track with it since I added it.
