was wondering if i can go with the dfuser 18k mod and then a ts chip on top of that....running stock hpop stock injectors and stock fuel system
:whs the TS style chip will do what the 18k mod will do but just with the tuning. You can not stack ANY kid of chips/tuners on a PSDNo point in doing it. That TS chip will set off the P1211 code, because the stock HPOP can't flow enough oil to stock injectors when they are running full tilt.
Adding an 18k on top of it will only trigger the code sooner, but won't give you any more power. The HPOP can only put out so much oil, after that, it just sits there. No amount of resistors or foolers will make it put out extra oil.
