What are some of the performance changes some of you have made to make your silverado faster. Thanx for your input.

1. K&N air filter
2. Replace fuel filter
3. Jet II
4. Hyper Tech running at 87 octane
5. Low temp theromstat.
6. Optima Battery
7. New power wires for number 6
8. Removed all the air filter chambers for noise.


For 3 & 4 running together you will need to use 93 octane.
Hyper Tech at 93 octane has less HP than Hyper Tech 87 octane and Jet II.
