So i just started my mods with a airaid jr and airaid tb spacer set up on my 5.3 in my 2011gmc. Im also planning on a superchips cortex or and custom tune. My question is if it is worth spending the money on msd ls plug wires for the truck too. When i put them on my nova it made a world of diffrence but thats a old school set up with a hei.

 

return the tb spacer it is wasted money imho

msd wires are a waste of money when it comes to.hp gain vs bang for the buck. the wire is short there isnt really a delay in spark.


as for the handheld tune it is a waste of money. full custom tune is the way to go.

 

^^^^^^^^ agreed

 

Agreed x3.

 

X4.

Sell your TB spacer on gmfullsize, they love that stuff

 

hey whats that supposed to mean??!!

(yes i frequent GMFS and have TB spacer. but mine was free and i know it don't do squat)

 

^^^ they make a whoosh sound, well kinda.

 

Msd wires are worth it.

 

...or turn the TB spacer into a nitrous plate..

 

Phantom, are you trolling? Or do you just go against what everyone says? I came from the lsx car side, and anything msd for the lsx family isn't worth it.
