ok i have a couple questions : here goes ...

i have a 07 nnbs silverado these are my mods :

Wheatley Tuning
K&N CAI
PaceSetters Lt's (full exhaust)
Cutout (if it matters)


and my questions are What kind of numbers am i putting down to the wheels? with my current mods ?

And do you guys think ill break 13's my best time so far (BEFORE HEADERS) is a 14.27 i havent ran my truck since the headers.

Thanks In advance.

 

did you get a tune after the headers?

 

those are strong times for no cam or power adder.

 

definatly those nnbs have stout motors, i know a guy with a 4.8 with exhaust only he ran a 15.0

oh and to answer your question, yes you should see 13's expecially if it has been tuned after the headers

 

Yeah, you aren't far from 13s... And traction problems...

 

yup yup yup u will see 13's

 

well right after i installed my headers i Had NO Performance Gains At ALL so i called Charley Wheatley And Told Him I Need A ReTune For Headers And He Said the Only Thing He Could Do is delete the rear o2's i was like WTF i spent a lot of money on these headers diddnt give me any better performance of not WORSE ... I was depressed so me and him drove around and worked his magic ... it was a little bit faster (mind you it's 5 o clock traffic and 100 degrees outside) so i was happy i guess THEN driving down the road i threw a code , i had to drive half was back to him he hooked it ip and it said Throttle Body Problem ... **** !! so he worked his magic again no more code ...

so i drove my truck for about a week STILL with shitty Performance then one day

da da da da da Crank Crank crank .... Very Hard Start (aww **** ) anyways not to make a long story even longer i took it to the Stealership and it was my fuel pump they fixed it under warranty (Thank God) and ever since then it's running like a beast so im just waiting for it to cool off befor a get some numbers , i dont want to be dissapointed lol

 

ALSO what kind of numbers do you think im puttin down to the wheels ??

 

is it a recuglar cab? if it is then you'll be well into the 13's...

 

Is 2wd or 4wd? I just had my dynoed before I do the mods to get a baseline to see if I do any good. Mine is 4wd CC I only put down 255 rwhp and 251 rwtq. Right now it is stock with Wheatley tune and Magnaflow cat back single.
