Ryan85 Posted October 15, 2015 Share Posted October 15, 2015 Hi new to forum did a quick search **** findex owt so thort I'd ask. I recently had my 2008 wrx hatch remapped and the mapper told me he cudnt get the turbo to boost he sed he wanted 1.7 but only got 1.2 so not as much power as I wud av liked he told me it's cos it's on fully synthetic n I shud use semi synthetic oil seems strange to me tho any ideas? Also car has turbo back exhaust n piper cross panel filter Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 Who mapped it? Never heard of oil holding a turbo back from boosting. Quote Link to comment Share on other sites More sharing options...

stants Posted October 15, 2015 Share Posted October 15, 2015 Agree with ghost, that's a weird thing to be saying, the only thing the oil does is cool & lubricate it, has should have no effect on what it spins at, they rotate at 100,000 rpm plus so a different oil shouldn't make a blind bit of difference, I've been told fully synth is slightly less viscose than semi so in theory according to your chap it should work better ? What kind of power are you after ? A 3 port boost solinoid would help control the boost better,did he give any indication of it was holding ok or bleeding off stx Quote Link to comment Share on other sites More sharing options...
Ryan85 Posted October 15, 2015 Author Share Posted October 15, 2015 No he did the give no indication of holding or bleeding off n at min it's round 250 mark was looking for 270 280ish power wise and as for oil I took it as him talking **** to be honest Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 Most mappers offer a 30 day "return" policy. May be worth considering that if possible and take it for a second opinion. Quote Link to comment Share on other sites More sharing options...

Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 Did you see the afr? That could be why the mapper wouldn't push it. What supporting mods do you have? Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 Also, what fuel was it on? Quote Link to comment Share on other sites More sharing options...
Ryan85 Posted October 15, 2015 Author Share Posted October 15, 2015 Don't no wat afr is lol n full turbo back exhaust n panel filter Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 Air to fuel ratio. If the fuel pump couldn't keep up the mapper won't push the turbo at the risk of running the engine lean. Has it been decatted? Quote Link to comment Share on other sites More sharing options...
Ryan85 Posted October 15, 2015 Author Share Posted October 15, 2015 Get wat u mean with afr nar n no dint c it n yes both cats av been removed also forgot to say earlier run on 97 octane cos Shell n testing to far from me Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 The fuel plays a part too. Lower octane is more prone to producing detonation(knock). Again the mapper won't push the engine far enough to constsntly knock and regard the timing. Fuel can contribute anywhere up 10-15hp Quote Link to comment Share on other sites More sharing options...
quit Posted October 15, 2015 Share Posted October 15, 2015 Use a proper Subaru mapper is my advice Quote Link to comment Share on other sites More sharing options...

classic mica Posted October 15, 2015 Share Posted October 15, 2015 Fuel would hold it back, but still should have hit boost as if it was Honda vtec getting dyno'd or mapped it should still hit vtec. Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 I think it was boosting. From what I gather he got 1.2bar but wanted 1.7bar. Quote Link to comment Share on other sites More sharing options...
classic mica Posted October 15, 2015 Share Posted October 15, 2015 I think it was boosting. From what I gather he got 1.2bar but wanted 1.7bar. Ah right, what was the standard uk imprezas running when they first came out? I.e, were they any specifics, not sure what I'm on but feels quick enough when I hit boost lol.

Scoobyghost Posted October 15, 2015 Share Posted October 15, 2015 0.9bar for classics. Not sure about later models or ppp type add ons. I'm at peak of 1.4bar with map. Quote Link to comment Share on other sites More sharing options...
