Default l9h 6.2 cam swap

hello, long story short I added the lsa blower, long tube headers, and lsa blower to my 09 Silverado with 6.2. well I took the blower off because it was horrid mpg while pulling loads as most of the time it would be in boost. so now it is a na truck with ls9 cam in it. well I really do not care for the lack of down low grunt so it gear hunts and still not all that great of mpg compaired to the stock vvt setup. wondering is there any good vvt cam that I can pickup decent power along with the same or better mpg?

Same or better than stock MPG?

You can do a lot better than the LS9 cam as you had figured. You will want something on the smaller side to accomplish what you are after.

yeah like with stock vvt cam in when I would do 65 no wind I could see 20 pretty easy. now I see 18 going down hill with a wind behind me and any faster then 65 it drops pretty quick, along with now down low grunt.

Comp has some shelf VVT cams that are mild.

Check out the 401 cam if its bottom end power you want.

Did you add timing back to the main timing table after getting rid of the vvt? I had no complaints with my ls9 cam. Towed fine and got better mileage then when I had stock with vvt.
