I recently put a skunk2 im and tb at 70mm. I did notice a difference but not as much as i had hoped. Mainly in the mid to high end.
It also seems to have improved it slightly in the low end as well.
Ive been told the most noticeable gains are seen when you get a chipped and base mapped ecu. To do that though you need to convert to an OBD1.
Does anyone have any info on doing that.
Should i use a p28 ecu or a pr4. I dont know a whole lot about the ecu side of things.
Any help would be appreciated.
