I had standard yellow injectors and swapped them for pink sti injector. I only drove it the once and once I realised that it wasn't running right I crawled it home and I only turn it over for bit now and then just to get the fluids moving. But I haven't driven it since

I suspected it was something to with that i just wanted to check, its not my daily so i think i'll be safe and when i take it to get mapped i'll make sure to stay out of boost. Thank you for you help.

Hi all you Subaru gurus I'm hoping you can shed some light on my situation. I recently made some preparations to my car ready for a remap and to hopefully get some good gains. but my issue occurred after i upgraded the injectors and fuel pump, the car runs and idles fine but when it gets into boost the car bogs down and i suspect this is caused by to much fuel and not enough air but i could be wrong. but as i said this is prep for a remap and the mixtures can be sorted out when mapped. i just wanted to know if anyone else had this issue when doing that same mods. and if there is anything i can do to try and resolve the issue myself prior to taking it to the dyno i.e wind the boost up. Any and all help will be appreciated. Thanks in advance.

they look like this

that doesnt look bad mate what make is it? ive gone for the prosport evo (evo is the model of the gauge not the car its for) gauges i think they look real sexy just waiting to get 2 more to fit them in a triple pod holder that sits in the center of the dash

what boost gauge have you gone for?

yeah my first guess would be the center allen head crew in your 2nd picture if its anything like my GFB BOV then unscrewing that will soften the spring on the piston and require less pressure behind it to release all that BOV noise goodness

i bet that feels nice when it pulls :) what turbo have you got on it? has the BOV ever produced a good noise since you fitted it?

yeah i'm hoping so my biggest worry i end up blowing my gear box as they're only good for around 350bhp but i get close to that ill be a happy man :) i'm not sure what else to suggest then mate i did look at the blitz BOV before choosing my GFB one as blitz is tried and tested i hope you find a solution you could always give Allen Jefferies a call and see if he has any ideas as to what might have caused it

im planning on a 3" turbo back decat exhaust (which my neighbors will love) im looking at getting sti injectors and an upgraded fuel pump and to top it all off a bigger turbo but hopefully one i can use with the top mount intercooler as i dont want to chop parts of my car off to fit a front mount but ill have to wait and see what turbo i end up choosing :) have you looked to see if there are any adjustments on the valve itself i have a GFB dump valve on mine and its just a case of twisting the body of the valve to alter the adjustment

thanks for the reply im planning quite a few mods that will include and require a remap and im just weighing up my options at the moment i hope you manage to resolve the issue with your dump valve i dont suppose its an adjustable one between atmospheric and recirculate? ive heard mappers have been known to turn it to recirculate whilst mapping to save their ears abit this will have a big impact on the noise it makes

hi there im afraid i cant really help with your dump valve issue but i was just wondering what you make of the mapping you got from Allen Jeffery as ive heard some horror stories and some high praises about mapping done

ill be decatting my exhaust when i upgrade the exhaust system to a 3" system so ill have to get the lambada sensors switched off by the ecu when it gets mapped what fuel pump would you guys recommend?

thanks for the estimate ill just have to wait until its dyno'd to see what i get from it do you guys have any recommendations about what lph fuel pump i should go for to go with the standard injectors on my wrx or should i just get the wolbro 255 ph pump?

do any of you guys know what sort of power gains i would see from a tdo5 conversion after its been mapped with the turbo a 3" exhaust system and a 255lph walbro fuel pump?
