I HAVE A STOCK LIGHTNING AND NEED TO KNOW IF I CAN ADD THESE MODS FIRST WITHOUT GETTING A CHIP ?

1. RAM AIR KIT
2. BASSANI CAT BACK EXHAUST
3. LINE VALVE MOD
4. DENZO IRIDIUM PLUGS
5. BOOST BYPASS

OR WHICH ONES ?

ALSO WHEN I'M READY TO BUY A CHIP. IS IT A GOOD IDEA TO GET A CRANKCASE BREATHER?

 

nothing you listed requires a chip

 

WHAT ABOUT THE BREATHER CAP ?

 

Yes, That requires a chip.

 

YES THE BREATHER CAP REQUIRES A CHIP!

And now we can all stop yelling...

 

THANKS FOR THE ADVICES GUYS.

You could also do a #2 lower pulley if you can find one.The stock program runs rich enough to support it safely.
