Well I went to the track last night with my $500 dyno tune in and couldnt get lower than a 12.90. I put in the 93 pulley tune from my predator and some 110 and ran a 12.83@106. I gave it a little more timing above 3500 rpm and went 12.75@107. All of my 60' times on all passes were between 1.80-1.83. The timing never went above 18 degrees. I couldnt here any pinging. Just makes me wonder about the shop that tuned my truck. So my question is about the wideband o2 sensor. Are they worth the cash? Does the sensor hold up with race gas? Where is the best place to get one?
Went to the track last night.

yes, yes, and the cheapest ive seen is the aem from rpm outlet. good runs, your tuner may have been playing it safe on your base race tune did you try and tweak on it any?
those are good times. what size pulley are you running. if its a #4 id say your doing darn good for the set up. if its a #6 its still pretty darn good, but could be a touch faster. (all my info is what i have read online as im no drag racing expert)
My custom tune was locked. It wouldnt let me in it. I have a 6# pulley
Those are still good numbers with the 6lber
