[DeTomaso] iPhone dyno apps

[Boyd Casey]

Has anyone tried any of the IPhone or Android dyno apps ( like Dynolicous)?
If so how did you like it, which one did or do you have and how accurate do
you think it is?
I have been reading Holley Tech manuals and would like to be able to
determine if I am gaining any performance improvements in 0-60 times. I
have readjusted my floats and now my car no longer stalls on hard breaking
without using the hose to join the vents.
