hi all, just looking for a few opinions on whats going on with my xr6t, ok so its a ba , auto , process west stage 3 cooler , bosch 404 with surge tank , heavy valve springs , 4inch dump into twin 2half inch , high flow cat , 60plb injectors, tuned by clint , profile autosports, he has done a brilliant job , from what the car was when I bought it to how it drives up untill today has been an exceptional improvement , 321.2rwkw on 19psi , box has been tricked up also , ok so I had a great play with a supercharged ford ute yesterday , probably the hardest I have pushed my car for a while , and just this arfternoon I started noticing a distinct lack of power, the turbo seems to be screaming ? its making a sort of high pitched scream when I have it on full noise , also its only reading 4.5ish psi on full noise , I have a eboost2 in my dash and I has been on 19psi for the last 8 months or so, since I had it turned up and tunned , the motor is running perfectly , it idles and has the normal power under the turbo , but is only boosting to 4ish psi ???? I checked all the pipping from the turbo to the intercooler and to the throtle body and it all seems fine , so? buggerd turbo ? replacement options ? I had a look at a few aftermarket turbos , if I whent one of them would I need to get it tunned again ? cheers all
