Are those figures with your Magnaflow exhaust Obie or have you refitted the originals? Also what gear did you do the 40-70 in? It will be interesting to see if there is much change after you have fitted your choice of free flowing exhaust. When I changed to the G56 it certainly felt like an improvement but you will have some figures to show if that feeling is correct. The only figures I have seen are Morgans publicity fantasy numbers, at least these are believable, thanks.
I agree with Bunny, your steering wheel splines sound like they are rattling LightSpeed. It is a common problem with the Lifeline QR but you may have a Traven one fitted? What ever type you have, make sure the wheel is fully engaged and not sticking on the splines, it will be more difficult to fit with the masking tape but should fix the rattle, if that is the problem.
