TVS 1900 09 Avalanche by AMS

[Larry@AMS]

2009 LTZ with 5.3 / 6L80E

The truck is a very nice daily driver, but was lacking a few things so the goal was to increase HP/TQ as well as appearance/handling while not compromising drivability or the ride. We chose the Magnuson TVS route combined with some suspension upgrades and the customer is more then pleased with the results

LS2 injectors

We are already planning a pulley change, C6 Z06 brakes and a custom fabbed HE reservoir for the 2nd battery location later this year.

So Keith pulled the trigger on this, nice! I thought he was going with the 2300, but I also thought he had a 6.0 in there, so what do I know..ahhaha

 

[Larry@AMS]

ha! yes he did and you were all wrong. LOL

I'm sure you will see it sometime soon.

These things have 2 batteries?

This truck does not, but I believe an HD does and therefore it leaves the extra spot empty.

Looks like stock junk to me...
