June 24, 20196 yr shes a 97.. gc8 ej20 ....uk2000 have recently bought a new subaru. was leaking at cat so had decat done on the factory cat. since then i installed turbo guages which show its running 0.5 bar boost and no more. actuator seems stiff checked solenoid (2 port) seems ok could it be a lack of backpressure at cat would a remap fix this any ideas. havent checkwd restrictor pill hole yet but if disconnect the actuator she runs over 1.4 so its not the turbo or fmic. i did find a hole in fmic patched it with steel stick and wrapped it in rubber to prevent further wear on pipe.

June 24, 20196 yr From memory a 97 UK turbo has about 220hp and only runs 0.6 bar from the factory , so quite possible it's running the correct amount of boost . Running a decat and fmic but not being mapped is quite risky and could lead to a expensive rebuild . Personally I wouldn't drive a scooby on boost with those major breathing mods until its mapped . The standard tdo4 is fairly small and not really suited to a fmic , they're much more responsive on a tmic . Due to the extra volume of air needed to fill a fmic and it's pipework (bigger turbos fill the fmic quicker)
June 24, 20196 yr Author fmic came on the car... il be after a tdo5 in the future. so it can sit for now.... so you reckon the remap will sort it.?.. not the first to say that but the td04 spools so early u cant really avoid some boost on normal driving... just get remapped asap then savage?

June 24, 20196 yr Author yea standard 220 ish. gathering funds for remap as dont know if has licence or not bob rawle does be over here the odd time tho so hel be doing it
June 24, 20196 yr Not too sure if that chart applies to your model , as it says my 00 at the top and no year difference on the UK turbo section ? . Some of the sti and other model ECU numbers don't look right to me either but I could be wrong . Was fairly sure my old UK v3 ran 0.6 bar before I had it mapped with a esl daughter board up to 1.4 bar (265 hp) but that was almost 10 yrs ago lol . With those mods it does need remapping and you'd certainly get more power /higher boost target but it's difficult to say if that will "fix" any issues Bear in mind The tdo4 and grey injectors will limit the remap numbers to sub 290hp . Might be worth getting a smoke test done ,to make sure non of the other fmic pipework or inlet tract is leaking boost first . As I may be wrong about the standard v3 UK boost being only 0.6 bar. The other possibility could be that it's in limp mode due to the mods , most models will only run 0.5 bar if the ECU senses something running outside its base map parameters. As I said before, i personally wouldn't be using boost on a scooby that's had a decat and fmic fitted without being mapped . If it leans off or overboosts there's a good chance you'll be footing the bill for a rebuild, which is much more costly than a esl remap .
June 25, 20196 yr Author thanks il get it done soon cleaned the actuator there. and waitin on an upgraded radiator coming so she off road atm anyway til i fit that. thanks il get it looked at asa
