It depends on what your chip is programmed for. Stock is 39 w/ vac line disconnnected. W/ the tta regulator it is 43. I think most chips are burned for ~43, and you can fine tune yourself.

Thank you...Mine was 30lbs with line on I think around 35 with line off???? Bumped it up to 40 and the car runs alot better. At 30lbs I had good o2's,no knock, and blms were a little high (138-140). No real changes except blms when I bumped it up to 40lbs?????????
