You in NJ? If so, what shop you going to? For a baseline run i dont think there is a differance between 3 pulls and 4 Tuning, sure, you can adjust stuff in between, but i'd imagine if you're not putting down the numbers u want by round 3, you arne't going to see an improvement by round 4 or 5.
Go to the track for now and save up some cash for the future. I'm sure that some shops around there will have a dyno day sometime this summer and cut a deal on 2 pulls or something like that. You can get the baseline then.
Oh yeah i forgot to mention my T-lock doesn't work. Its been crapped out since i've had the car I think. I can only lay one strip of rubber i'm in the process of fixing it before i go to the track.
Freakin rear-end-rebuild kit costs $100 from randy at MD and $130 from ford! crud-o-la
mini spool dude. forget T-lock. i am making the real traction change. i have a low milage t-lock in the shed, but crap t-lock breaks at 180 lb-ft. (one wheel breaks loose at a difference of 180 lb-ft to one axle).
i need real traction. i isn't for daily driver's but i finishes the one wheel peel crap. mini spool in a few hours. it replaces the spiders,clutch packs, and springs. the axles lock directly to the spool. no need to remove the gear.
altitude correction corrects high altitude high temperature conditions to 69f 29.95 at (mean)sea level. it's a way to know how fast a guy in the rocky mountains at 95 degrees compares to sea level at 65 degrees. i don't have the formula handy. density altitude has a major effect on power.
ohhhh I thought you were talking about how some people guess your power from MPH. I knew about that lol. I had a friend that went to the track with me. before the new engine I trapped 98.. after 107. He said it looked like a 70-80 HP gain. I thought there might be some method to that.
