OK new here. I have a 2000 scsb 5.3. it has Cai, no muffler, Diablosport, 4.56 gears, vette servo, efans, on 30 in tires and It's not lifted. I ran last night and could only run a 16.3 at 82mph I always see guys on here running 15 sec on here stock. What am I doing wrong the only thing i can think of Is that the elevation is around 5500 feet. Any help would be great

 

Yes elevation plays a huge role. Also ditch the diablo sport and get a real tune from someone reputable. Post up your timeslip that will also help diagnose

 

I would get a custom tune on my truck ran a 14.1 just CAI tuned by me PM if you need any help

 

DA is more important than elevation.. but you mph should be around 90mph

hell my truck traps 82mph in the 1/8 and its slow


also post up the rest of your slip

 

The elevation IS killing you and possibly DA as said above. Turbo is the answer in a mile high scenario!

 

ask around what trucks are running in that same track..many guys here are from texas with really low elevation...my track is at about 5800 ft nd i compare my times to trucks here...altitude will kill you bad...stock rcsb 5.3 run 17.7 here where i go

 

r/t was .492
60' -2.513
330- 6.916
1/8 - 10.539 at 68mph
1000- 13.667
1/4 mile 16.358 at 83.04 my

I went and dynoed it yesterday it put down 263 hp and 304 tq it had a good power curve all the way up tell 5200 then it falls off.

 

60ft. You should be able to at least 2.1-2.2 60 that thing

 

What is a CAI?

 

Cold air intake.
