    Break torquing to about 2k rpm would help at launch. Also some mods that will gain you increased low end torque would help with this as well.
     
  3. for example? low mods?

    Advanced timing "+2" should help with your low end TQ

    lighter wheels + tires for weight. the stock wheels (18s or 20s) weigh close to 40lbs each plus the tires. that will save you a lot. Forged wheels or lightweight 19s will weigh around 20-25lbs each, right off the bat thats over 60lbs shed.

    If you are going to the track, take out the spare tire and tools and that will save you another 50+ lbs.

    your stillen catback is kind of an over kill. 3" true dual is too much for the FX35. you will have made some horses up top, but it has really ruined the low end power. its your car but i would suggest a single exhaust no more than 3" throughout (either nismo, HKS, custom?). that will get you out of the gate a lot faster.

    a set of test pipes or HFCs will unleash a fury of midrange to up top power. my fast intentions test pipes weighed around 13lbs for both i think. each of the stock cats weigh more than that (more weight savings)

    after that a good tune will give you a few more ponies as well, and set everything in order.

  8. don't worry about tunning my ECU for gas propane is totally programable, my tunning is excelent, i have better results with 105 octane rate of propane instead 91 octane gasoline.
