Bud, something is wrong with the car! After branches and chip, its barely making stock power! Im sick of spending on this car, i don't know what else to do as there are no faults whatsoever other than the 02 sensor thats buggered but I doubt thats any reason for power being down. Im just going to get the one sensor replaced,they want to just change the pipes to mandrel bent pipes as these cut and weld jobbies into the boxes are also restrictive. Once all that is done,will post new dyno graph. The current one is pathetic really.
