13.5 at over 100 sound good for a bolt on DD, when are you hitting up the track

 

I agree these are good numbers, however some bolt-ons and certainly a tune will void factory warranty. I am looking at factory vs. factory numbers at 87 octane. I am in sales and my employer pays my fuel bill so I am somewhat concerned to both pay more per gallon (checked today and premium is $.40/gal more than regular) AND possibly get 1.5-3 MPG less than my current 5.3L is getting. Just don't want to mess up a good thing but definetely want to upgrade my truck both in power and features.

 

I see what Ur saying

Btw. He only added 4 degrees of timing from 87 oct tune... Before he started getting knock

 

Thanks for the info, I feel I'll end up with the LTZ package with the 6.2...just weighing out my options now.

 

post the dyno sheet so the other owners of modded 6.2's don't call bullshit.

 

You two guys have almost same set ups, and almost same hp/tq numbers. Only difference is he has a asp UD pulley, which give him that little extra bit. And it could be a diff dyno

 

im not calling bullshit just yet. that will come down to track times.

dyno numbers sell parts.

 

Very true, I'm still waiting on a good track run with my truck. Either way I'm sure both of your truck haul ***!

 

I can't post pics. Don't know how
But I can email Dyno sheet to someone. B a iPhone pic


Remember. Stock catback still

4kmiles

Ill get good track results. I've owed a couple 10 second 6 speeds surely i can drive a auto

 

sent it to me, i'll put it up for ya
