02 ep3 with k pro ,
turbo ebay kit with rc injectors car has an exhaust leak who is going to be fixed tomorrow at the down pipe's flex pipe, when you floor it car reads lean about 13.89 sometimes at the end of lets say 3rd gear pull boosting around 7.5 to 8 psi, cheap ebay boost controller and it fuel - cuts around 5,500 rpm when WOt and boosting..
it has suppossibly a decent street tune before the exhaust problem , and my really concern is will this is exhaust issue affect the car that bad because maybe the air/fuel ratio read by the o2 sensor is that off by the exhaust leak, or its just a bad tune, or should the car be tuned again after leak its fixed???

okay we took the car to the muffler shop and told me car was leaking from the gasket beetween the manifold and the waste gate, could this be the problems why the car is acting up? is not a bad tuning then correct?
