Good luck to you guys that are heading out today! Wish I could make it, but I'm stuck at work, and my truck is still apart. 
Milan test and tune wed 16th
- Thread starter DieselmafiaLLY
- Start date
Ok so I was able to squeeze out a 12.76 at 108 now my first issue was getting a good 60 time, for some reason I could not for the life of me get traction here, spun at the top of first and second, tried to launch at different boost levels aswell as changed tire psi, started at 30 in all and was down to 26 but same issues.
I think I have figured out some of the issues right now, #1 I believe I have a boost leak from somewhere, thinking intercooler and #2 a weak cp3, it would only hold 21k rail when the tune was asking for 26k but not something I cant fix
would like to hear from you guys on what you think should be my next steps in getting some better times, thanks

What boost pressure were you seeing? For reference, I have the same turbo and it peaks at 38psi and maintains 36psi, my gauge in tapped in at the Y bridge. Also was the launch violent or a smooth transition with a lot of wheel spin?
I would work on reducing the 60’ time; a couple of tenths here will have a significant effect on your E.T. Was this your first time at the track?
I saw the same boost levels and gauge is on the intake. on my launches I was getting wheel spin at the top of first an second....didn't matter if I left at 10psi or 20. this was my first time at the track with this setup, I believe part of the issue was my almost worn out michelin mtx's
I'm thinking I may have been launching with too much boost and blowing the tires off which gave me such a shitty 60 time, my thought right now are possibly rancho 9000's or Qa1's and some drag radials to get me better suspension and traction, but I am looking for some suggestions on your experience and what you guys recommend?
forgot to mention earlier I did blow the coupler from turbo to boost tube on one of my runs but it may of just not been tight enough.

I usually launch between 15-20 psi and have had good luck. I'm running 305-50-20 420's though. I cut a 1.64 60' last time out and ran a 12.24 with a very similar setup to your's. The Rancho's will help.
Yeah new shocks will help and check the preload on your traction bar. I run your basic 265/75R16 Michelin A/T’s at 30PSI front/rear and cut low 1.7x 60’ on average with a best of 1.63. I can't tell you what PSI I launch at because, truthfully I don't pay attention. Last year 2nd gear launches at ~1800 Rpm worked the best and this year I have a higher stall but haven’t had a chance to test it. What will really help is getting back to the track and playing around with your setup. I would hold off on the drag radials for now because they'll hurt you on the big end. Also keep in mind that Wednesday probably wasn't the greatest day for traction.
I think part of my issue was my almost bald tires....gonna buy new ones and have some other things I wanna try, hopefully before the season is over. If I can get the funds together might get dual pumps
I am deff going to hold off on the drag radials till nxt year
