2013 gt500, id1300x, Vmp baps, Jlt 123, whipple 68mm, off road x. As the title says, haven’t had the chance to put my 2.4 pulley back on but the tune is written for it, getting p0172 and p0175. Any chance the stock upper is the cause? I thought it wouldn’t be a problem until I get into boost.
Thanks in advance
