HI,

If you fit a different cam to what the chip was supplied for, the chip
will need alterations, as anything which alters the engine volmetric efficiency eg cam, turbo etc. will cause AFR changes, regarding the
turbo only by checking the a/r etc,, unless you know the car's
history, maybe better to leave the speck as it is, considering it has just
been setup and running sweet, unless you want to spend some cash.
