id say ur numbers are fine, get that thing tuned and you will see 15s. on a side note, how is byron? im originally from Il and want to try and run my truck there next year. we see some really high DA here in the summer and would love to see what my truck can do closer to see level. good job getting baseline times, it will be fun for u to see what each mod does for your times, good luck!
