Hi all,
just a quick one on this, trying to help a friend ona tune but it has been done so many times by different tuners (an none right) that i'm chasing my tail.
One thing I notices was that the IAC air flow has been shifted to the left so less steps gives more area, by about 10 square mm the 0,2,4 values are zero, rest are as stock but shifted (the throttle body has been changed to a BBK 80mm one, does this still need to be done, I didnt think there would be any difference if IAC is still same and hole it still same size?) Also, the park position is set to 310 steps, but in my stock 99 tune (and his is a 99) it is set as 310 ?? Does this make a difference also.
