i jus bought an 07 sc/sb chevy truck it has the 5.3 and a posi rear unit thats about it to make a long story short i know nothing about these trucks at all i wanna know what is worth the money as far as mods go it still has about 90,000 miles of warrenty left so nothing to serious also i heard you could tune these trucks and get more than a hand held would . does anybody near me do this i live in greenwood. any info would help thanks

 

you can go with a mail order tune from Wheatley...... he is a sponsor here and is from the Houston area... if your truck doesnt really have any mods than a mail order tune is fine since he has done lots of 07 chevy's .......
