    Default installing higher 2500rpm tc, tunning ?

    I have an lq4 6.0l with a 4l60e. We swapped in a lq4 in a 98 suburban and was wondering before this is all finalized if i have to change anything in the tune relating to a higher stall of about 1000rpm. Thank you. Eric

    May have to pull down a little the WOT shift points (both WOT MPH and WOT RPM).
