It does not run terrible. Slightly slugish from a dead stop but I always assumed it was trying to flood itself out. The idle isn't terrible. It is higher slightly than I understand it should be. And the only reason I would say chip it is because I can buy a chip for 100 bucks and use my soldering skill on a spare ecu I have to do it myself as opposed to spending say 500 on a set of injectors then the conversion kit on top. If it will run fine with a chip for a few months then grea. Like i said I do plan on swapping it out.
