barometric pressure. affects the conversion factor of the dyno. Dyno measures power at the wheels then calculates back to give a fly wheel figure.

I'm not even gonna say who my guess is lol

Not sure whos down that way tbh. Do you know who mapped it? Shouldn't look like a roller coaster and while fueling is ok the boost is doing strange things as well, typically it will peak then drop off up the rev range as it runs out of pull, not rise up the rev range. Although ignore the fueling and spool (was when my engine was fooked), see how the turbo peaks then slowly drops off, thats what i would expect to see

One figure is at the fly 294, one at the wheels 248. However looks like whoever ran it doesn't have a clue what they are doing so could be way out. First off it should be in shoot_44 mode on the dyno, not 4f, also its been run in gear 4 where as a wrx 5 speed should be 3rd. (unless they put the info in wrong). My advice, take it somewhere that knows how to operate a dyno properly and get it rerun.

As above, have to get it mapped for crap fuel :( still not ideal :(

No no no. Stay with v power or tesco 99. Don't risk your engine.

lol, have to say i love dump valves, although not very keen on chirpy blow off valves

good choice :D

looking good

Ah get to the end and it says minimum 99 ron on that one

Dunno, all the quotes i could find direct from shell on the threads say its 99 :S

hahaha, mate has one of the new ones, sounds good, bit quiet and handels like a pig though lol

hmmmm, no V8, tut tut,,,,,, But could be worse, could be a honda,,,,, hahaha

Welcome. Tbh its more honda that is a stoning offence,,, although which engine is in the mustang?

Shell are still saying its 99ron, there was a load of questions about it raised (mainly on the gtr forums iirc) about it about 12-18 months ago. but word came back nitro+ is indeed 99 ron. Vpowers predecessor was optimax and that was 98ron, you thinking of that?

Can retrofit if you want plus eurospec have them as some countrys have to have by law them so i understand.

bumper is the same on sti and wrx, some have lip spoilers and sti typicly has no fogs, although fogs were an option. Only difference is the inserts

Could be various things, but given its a 2.5 get ti checked out by a specialist who's independent of the seller.

Where have you got that info from?

hahaha :D

Well that post is buggered :S BP is crap basicly, stick to 99 ron only

what does the sound do if you rev it lightly?
