sounds to me like you need a new steering rack zoidberg . Autumn*** ( ) : 15;1 is leeeeeeeeeeeaaaaan (anywhere between 11.5:1 and 12.5:1 @ wot on full boost is 'optimal' and varies between tuner to where they tune your fuel map) , your ecu would be pulling all the timing it possibly can out , at minimum you need a safc , the extra 200cc your engine has would make a difference to tune btw , What type of fuel pump does your car have? if it's std it's a good time to replace it , go into the 'forced induction' forum and search rb25 , that will keep you busy for a few days . As for your brakes , does it have abs? , i had an issue with my 33 a few years back with the 'soft first tap' on the brakes , i traced it down to the abs unit , replaced it , and (out of luck due to it being 2nd hand) it fixed the problem , buying and fitting rebuild kits to your calipers makes a bit of difference too
