I am really looking to boost my mpg but I understand the two can go hand-n-hand. I welcome increased Hp but fuel mpg is my ultimate goal. Post your exhaust/ cold air intake/ computer chip/ etc. mod that boosted your hp or mpg. Post before and after real world numbers. I'm thinking I can gain about 5 mpg with a mild exhaust mod, CAI, and chip. What are your real world results?...

Thanks!!!!!

P.S., I have a 2002 Silverado, 5.3, 4l60.
