Well guys I was wondering what would be the best/safest way to go on my NNBS 5.3L with its TVS 1900, would it be good to do some spray or meth?
Let me know what yall think

 

Well, since we know nothing at all about your particular build combo..........





Lots and lots of both!

 

It's just a regular 5.3 with LT Headers, fully rebuilt tranny + Stall and well the TVS

 

METH, turn the boost up, make sure the tune is right on

 

How much boost? If you're still on the stock cam, that needs to be your next mod. I am also going to suggest a 2-bar MAP SD tune. What is your gear ratio & tire size? Which model truck(how heavy) do you have?

 

I doubt he's anywhere close to needing meth. I don't use it myself.

 

its a Crew Cab about 7-9 lbs of boost, rides on stock 20s with 3.73 gears (im trying to avoid the cam and not go internal just yet)

 

A smart cookie once told me to stick with your MAF sensor if you are not flowing more than it can handle.

 

Your right about that my tuner managed to tune it great with my stock MAF/MAP Sensor

 

Ya, with the stock cam and only 7-9 psi, stock MAF is good to go. No need for meth either, in my opinion. Add nitrous (wet kit) if you want a little more at the track. But bottle refills get old quick. For less money than a quality N2O kit, swap in a blower cam and get retuned. The power will ALWAYS be there. Then get a smaller pulley.

Damn, this process never ends, does it? lol
