Considering a test run this weekend.......predictions?
Thinking about sneaking up to the track this weekend for a couple test pulls to see where I am so far. Best to date is a 13.43@100mph before installing the bosch pump, StainlessWorks long tubes, and dual 3" exhaust. What do you think I can realistically pick up with the new MODs? Are 13.10's out of the question? Dont BS me.......give it to me straight, I can take it 
13.08 @ 102 mph

Not to great...but not to bad considering the weather. It was 80* here today and I only had time for one pass because it was so damn crowded. I waited in the tech line for over an hour to get inspected...
.
Anyway....with a very conservative tune @ 4.6lbs of boost (133kPa) and 14.5* of timing it went 13.65 @ 97mph. Hopefully next time i will have time to play with the spark advance and a couple more lbs of boost. Truck felt great though....top end felt really good. Not sure why the boost is so low today.....it peaked once at 139Kpa but only for a second or two. Maybe its the weather, or maybe its the new exhaust, i dont know. I have seen it hit 148kPa a couple times since the new exhaust has been on though so I dont think its that. Truck feels strong though...so even though there was no new best today I am pretty happy cause I know its got a LOT more in it. Oh and the new fuel pump did great. Stayed right at 11.60 AFR the whole run, even fell to 11.17 for a few frames.
My best run of 13.43 last year was in 40* weather with 6.6lbs of boost and 17* of timing. A few more degrees of timing and 2 more pounds of boost should give me a new best I hope.
