So the old dmax has 156k on the stock cp3 and its had a chip on it for most of it life (since 20k) so the cp3 has taken some abuse over the years. well after getting EFI Live and puttin some big tunes on it, i logged some data and can see im not holding rail pressure. on the big race tune im droppin to 17k with a demand of 23k. I have since had Mike (mmlmm) build a different tune that makes the most of this old cp3 but i wanna get all she can out the stock turbo while i save for twin turbos.
Now heres my delima. Should i buy a stock CP3? a modded cp3? or try a modded reg first?
i do not plan on makin much more than 600hp when the twins come due to the worry of shortening rods and when the time come to do a motor i really dont wanna be much over 700-800hp max. the twins are there more for towing and droppin egts while still giving me some damn good towing power lol. I also maybe plan on doin 20-40% max on injectors and only when these stockers are shot (which shouldnt be long as we all know how lb7s like their injectors for dinner).
so here i am in a delima. I go with a stocker and hope it holds the rail pressure i wnat but i dunno what a stocker can support up to. Or i get a wicked diesel stage 1 or possibly stage 2 cp3 and it should hold up to the modds im planning. Or i try throwing a modded reg at it and see what my stocker picks up to.
My only prob with puttin a modded reg on is i dunno how to tell if my stock reg is bad. under a commanded 160 mPa at idle i get 21k with a demand of 23k. my current tune is only 2800pw and its barely holding 20k at WOT. is there any way i can test the FPR without throwing a new one on or am i s.o.l? i hate to just buy parts and hope it fixes it. im a mechanic (not a parts replacer) so its really hard for me to justify just throwin a part on and crossin my fingers
thanks for the help guys. hope i gave enough info. if you need more let me know
