5.3 mods...what are the first things you should do???? air intake kit???? what about throttle body spacer???? programmer??? not sure ...help...thanks

 

TB spacer is a joke lol

programmer: good for adjusting shifts and rev limiter. As far as HP gains.. LMAO.. that sums that up

I didnt have my truck 30mins and had the muffler off and a dynomax round muffler going up in its place with clamps(got her welded later that day).

Next was the Volant intake from tbyrne.. very nice piece.. cant feel any gains, but its no way to feel gains unless its 20hp or so. You can hear the motor sucking more air though so i guess it works.

next will be a 00 vette cam.. installed a 01 ls1 cam in a friends truck today and that made a nice little buttgain up top in the rpms.

Then a TB 2600 stall

LS1 fans and LT headers are soon to come also.. i just want a 14sec NA truck lol

goodluck.. just dont get suckered into GIMIC mods like a TB spacer

 

I did exhaust then intake then tune then exhaust again.
