I can't turn mine down. can increase it but can't decrease it. currently setting on 5 KG but don't go any lower than that.

Take it to a tune shop ... or not... watching the threads progress to “I blew up turbo what to do next” would be great. 1 1 Link to comment Share on other sites More sharing options...

Head Member 74 Member For: 13y 7m 26d Posted 06/04/19 10:07 PM Share Posted 06/04/19 10:07 PM There's a restriction in the fuel return at the bottom of the pump module that has to be enlarged He doesn’t state what pump he is using, he’ll only need to mod the pump return if he is using a pump greater than a Walbro 255.Plus you guys are a bit harsh. 1 Link to comment Share on other sites More sharing options...

XR6T 520RWKW Member 40 Member For: 5y 1m 21d Posted 16/04/19 03:53 AM Author Share Posted 16/04/19 03:53 AM (edited) I have plazmaman Surge tank 1000 hp already installed connected to my turbo smart 800 fpr. I re-tuned my car coming off e85 to 98. and the tuner who tuned it was providing only tuning service and no mechanical service as it was only home service. my fpr gauge is showing 72 psi when I bought and still is at 72 . after doing my research I found out it should be at 4 bar plus the boost when turbo spool up I was trying to bring down the psi on my fpr but it don't work. the lowest it goes is 70 psi. I was told in the forum, to enlarge the return line by 20 mm but my fpr only has 1 line connected to the tank, second line for the injectors rails and 3 line for manifold ( I guess it act as sensor to tell fp to increase the fp when there is more boost). does any1 have this plazmaman fuel tank or do I have to disable one of the pumps . https://plazmaman.com/product/ford-falcon-fg-fuel-system-dual-pump-1300hp/ http://www.turbosmartdirect.com/Product-Categories/Fuel-Pressure-Regulators/FPR800-2017-Black.html# plz guys if you want to help me help other wise stop telling me to back off.
