Mapped car on normal Unleaded?
My car has been running a bit iffy the last week. (Bit hesitant, feels down on power and doesn't feel as if its coming on full boost all the way through the revs, just seems limp!)
I have thought about MAF's and coilpacks but it also occurred to me that it started the day I filled up with fuel.
I always run it on high octane fuel, but I had no where to go so the normal Texaco stuff was put in!
Do you think this could play a part in the crap running on a mapped car? (MTM Map)
