I just swapped my drag intercooler to a much larger greddy cooler designed for 240sx's. I will be heading down to the dyno in the next few weeks, but I want to know how much the bigger intercooler will effect my air/fuel.

Should I be worried about running too lean? Anybody have any examples of how much there air/fuel was off after they changed their intercoolers.

 

it needs tuning.

 

I know it needs tuning, like I said i'll be going down to the dyno sometime in the next week or two, I am wondering how much my air/fuel may be off.

 

well if the intercooler was completely unnecessary, it wont need any tuning.
or one might say, if its gonna make any more power, its needs tuning.
