just picked up an 07 chevy crew 5.3 going to start doing some upgrades and finish it off with a tune from blackbearperformance.com truck is stock now, where is the best place to start to get the sucka moving? thanks

 

Air aid MIT tube, drop in filter, exhaust, and longtube headers.

If you want more then a cam and torque converter would be next on the list.

All tied in with the tune

 

decided on going with the MIT tube and drop in and the exhaust.. headers... meh dont need to get into that... had headers on my dodge and they were nothing but problems... torque converter is a little to involved and expensive.. any personal preference on exhaust country_09? you seem to be the local guru...

 

do you want it loud or do you want it more deep and mellow?

and don't stray away from headers, these 5.3s get a LOT of help with headers. LPP from what I hear has a great set of LT's with an ORY for 400.00 i believe.
