This came straight to my mind too, have had this issue before a number of times caused by the oxygen sensor failing. not in a subaru but surely they do the same thing
Hey guys, a mate's evo 5 rs was stolen sometime last night from his driveway in Mt Wellington. Being an rs it had black door handles, no rear boot garnish etc. Its also had the factory wheels painted black. Had Evo 7 recaros too. There aren't many of these around so hopefully its found soon.
If spotted please call the police
The new pump was installed a few days BEFORE the reflash so it will have nothing to do with the reflash. I went for a drive with the op after he installed the pump to see if it was obvious but it drove as good as any stock v7 would, didn't notice anything abnormal. They did use the aftermarket deatschwerks filter sock on the new pump and i've told him to swap back to the stock one. He just thinks it was faster before the pump install for some reason. But the reflash was done a few days after this so now even i'm confused with what he's getting at
Didn't we discuss this today and come to the conclusion that it'll be best to just hold off till the reflash? Lol..why so impatient! Just do what evowrx and kwi_fozze said
Yeah fully understand and agree with you, have seen and heard of many different results from very similar cars over the years. Was just joke from a conversation I had with the OP yesterday
