I plan on running DSMLink starting next week and had a quick question. As far as fuel tuning is concerned, is it necessary to upgrade my fuel pump? I have mine rewired but I'm not trying to do any kind of damage. Is that enough? Thanks for any help. Peace 

). Timing was perfect, A/F was good. Use DSMlink's Air/Fuel calculator to stay below 12 to 1, and you'll be fine. From what I understand, 11 to 1 is "perfect" for what a DSM likes to run under boost, but is a little too rich for my blood.
