what times are you running with your turbo setup? (1/8th, 1/4 mile)
I just took my truck to the track this past weekend, a 1/8th mile. I'm running just the stock 5.3L w/ 60# injectors and a front mount MP70 @ 7psi
I ran a 9.98@75mph as my best run (1/8th mile), which using a conversion table to get a rough estimate- it is showing I would be running a 15.5 in the 1/4 mile I was hoping for at least 14's (low 9's in the 1/8th mile), 15.5 seems like a stock Silverado could run that lol |
are you running street tires and 20" rims?
|
What gears are you running?
|
7.82 at 88.39 in the 1/8th with a 1.77 60 ft.
In the 1/4 it was 12.37 at 104.87 |
Something is off. Get your tuner some logs to see if it's in the tune. I had a melted spark plug wire once and couldn't notice it cause truck still made good power but once it was fixed it was night and day.

ya, somethings gotta be off. i went to the track this past friday night for a test and tune, and with my headers, muffler, intake, i went 15.12 at 90.2 lol.

Nelson did my tuning (mail order tune), maybe I need to get him to tune it in person? |

here is a video vs an old stock Silverado... Turbo doesn't kick in until 9 seconds into the video http://www.youtube.com/watch?v=Bm5XvzyRPYs Thanks for the help guys, though I'm not looking forward to driving 7 hours to Nelson's shop! |
