Figures...LOL...thx for the follow-up.
No problem.
Most of those supposed chips that claim hp/tq increase are just piggybacking onto the locked factory system and alter the signals going to the computer which in turn tricks the computer into thinking it needs more fuel, timing which could create a little more power, but at the expense of voiding your warranty and possible engine damage.
Tuning is the only safe way to get more power, so until someone unlocks the computer for tuning all you can really do is improve airflow going in/out. The drop in K&N helps a little, but from my experimenting I found the biggest gains to be had were through exhaust modifications that allow higher flow. The factory exhaust is very restrictive and typically turbo engines don't like or need backpressure, but GM decided that a quiet exhaust was more important, nothing new with them, lol.
