I emailed Vinci with this question...
"I have a
2008 Chevy Suburban 1500 2wd with the LMG 5.3L (Flex fuel) engine and the 4L60E (4 speed) transmission.
It has 3:73 rear gears and I am running 285/40/22 tires (31" diameter).
I live in Northeast Florida (sea level).
It has an Airaid MIT intake tube and high flow air filter in the factory air box.
The truck also has a set of ceramic coated JBA Cat4ward (shorty) headers, no cats and a full exhaust through a 3 chamber Magnaflow muffler and has been custom tuned by Diablew with a Diablo sport tuner.
It is a 6,000 lb truck, I couldn't care less about peak HP numbers or high RPM. The truck is mostly driven around town with an occasional road trip with the family.
I would like to delete the AFM system and gain as much Torque down low and mid range as possible. I would also like some chop at idle without sacrificing vacuum and I don't want to change the torque converter.
What would you recommend for my goals (cam, etc.)?"
and this is what he said...
" I would recommend the VHP 553 camshaft. 208/216 530/530 113 +5A. It is designed for high torque gains with a moderate choppy idle."
The lope isn't a requirement for me but it would be cool if it had a little chop to it.
What do you think?
