Well I dont do a ton of reading on this stuff so im not sure how this is compared to other 5.3s out there. But its a 06 4x4 sierra with the 5.3 alluminum block. Has TSP 214/218 cam. Pacesetter long tubes. ASP underdirve crank pulley and GMPP Cold Air intake. Numbers were 303hp/315TQ.
Truck has 3:42s with 20inch "new style tahoe" wheels on it.

Let me know what you guys think

 

Almost identicle numbers that my L33 put down with boltons. Very nice

 

Badass numbers man!

Do you know how much those wheels weigh by any chance?

 

Good numbers, esp for being on the big rims....

Nice! How tall are your tires?

 

Um 31-32. There the stock size 275/55/20 duller hts that come on them from the factory.

 

Just wondering how it feels cruising on the highway.

 

Same here. Those are some pretty good #'s

 

Why the huge dip in torque between 3&4K RPM? Too rich or lazy timing??? who did the tuning?

 

Thing rips on the fly. HUGE dogg out of the whole. Plan on tossing in a converter. I did a few pulls from a sign with my buddies 6.2 denali and it puts like 3 cars on me instantly but seems to get some steem to catch up at about 45mph.
