racing that is in the ol yukon decided to join in on a lil TNT action tonite at the track....

i loaded about 5 of my street tunes i have been working on

first pass reloaded the last dyno tune programm into the PCM

16.67@82.xx 2.4 60ft

second pass i backed it up again

3rd pass i put a timing table tune in it
16.11@84.xx 2.4

4th pass i loaded was a timing and shift points tune
16.0x@85 2.38 60ft

5th pass loaded timing and minor p.e. lean out tune
15.91@87.7 2.36

6th run left timing and worked on AFR a lil more and tried stall against the vertor it didnt like it
15.95@86.4 2.48

7th run i leaned it out a lil more purely trusting the 02 mv's
15.88@87.3 2.3x 60ft



gonna try and get it on the dyno tomm to check the AFR and maybe see if i can get some more HP/TQ outta here

all this tonite was on the 20's as well and DA was horrid

 

not bad numbers for suv, especially with 20s

 

Not bad at all. The best my Tahoe ran on 20's was 15.1 @ 104mph and that was with a Whipple, stock tranny and 3.73's. Never got to run it after the other mods cuz it blew up too soon.

 

good runs jeff. i was hoping to go, but with the rain that came in again yesterday i knew the humidity would be through the roof.

 

nice times and good tuning to drop it all most a second.

 

so did you look at that tune i emailed you maybe try it in the ol whitey of yours

 

i gave it a look, but haven't had time to try it out. some of us have to work you know....

 

dont hate on me not working late this week or next im gonna be hitting the clock again

 

The HD would still take you out Stock tuned.
