New to this

[Cell2011]

I'm a little new to this. But I'm looking for a little help. I have an 08 Silverado 1500 with the 5.3..... Rebuilt the engine, 20 over, comp cam, not sure the duration, but intake and exhaust are now at a 500 lift, have a fast 102 intake with a 102 throttle body, k&n intake flow master 44 single inlet to dual outlet. Stock manifolds and cats. Has a 7.5 lift with 35 12.50 17 wheels. I'm trying to get the max outta my truck but still being safe. Tuned and dynoed pushing 198 whp at 5300 rpm and 202 ft lbs at 5400rpms hp tuner on a mustang dyno. With the 35s I'm sure I lost some hp, but the 373 gears should compensate some of that I would think. Just all that's done to the truck, I would think that my 200 whp should be a little higher, or does that sound about right? If so what can be done before ripping the heads back of

You have tuned it? A custom tune?

 

The fast 102 intake is overkill until you get fully ported aftermarket heads. Assuming you have a huge MAF also or are you on a SDT?

 

With your huge tires that will be a power black hole.

 

 

You might try to find a hub dyno in your area.
