I installed a big 28 on my stock fuel set up until my pump and translator show up. I have it at 9 psi and my check engine light comes on so i hooked it up to a friends logger and it gave the code p0170. This is fuel trim malfunction. Im guessing that my stock set up cant keep up but im not sure. If anyone can shed some light on the subject it would be very helpful. Thanks.
