Those are really good numbers And thats pretty cool you gained right at the advertised 100 hp with the N2O....I would do LT's and a cam next ..seeing as you already have good heads/intake mani...

 

x2. Makes the graph look like chit and I personally prefer rpm's on the bottom. Helps decipher where the power is made at

 

You must have a freak engine.. When I had just a tune/muffler/intake my 5.3 made 280whp. Now I have headers and im right at 300whp NA on a nitrous tune... My friend has an 08 5.3 with open stock Y pipe and 100 shot it made 360whp/415wtq, NA it made 270/280.. Just curious to why yours made the numbers it did. Seems kinda high, but hey anything is possible lol

 

Thanks! next mods I want to do are gears front and back with a 9.5 14 bolt rear end conversion and true trac. A Circle D built 6l80 then get a complete 6.2, swap it out with the 5.3 and put a front mount turbo on it. With those mods I think I will be happy, should be a pretty stout daily driver.

 

Trust me I was VERY surprised too I really dont know. Maybe because my 2011 is a aluminum VVT 5.3 and tuned great?? Truck only has 3k miles so maybe because its just new?

 

All dynos have a correction factor built in, and depending on how it is set, it will skew the numbers up or down...

 

It;s not possible but all dyno's are different and can read anything.

SAE or STD?

 

Considering the drivetrain in that thing, those are great numbers! Id be supprised if my tired out 5.3 could come close to 300hp NA.
