Hi there, just fitted a new VF34 turbo, sti pink injectors, turbo up pipe and walbro 255 fuel pump on my 01 wrx. before mods was running fine at 274bhp and running sweet, with only a remap, fitted new items today and on boost runs realy bad as tho its holding back. Is this due to over fuelling? or will getting the car back in for remapping help this prob? any help much appreciated! Rob

you need a remap you gunna **** it if you use boost get remap and drive very steady until its been done

You fitted those mods without a remap are you mad

Needs a remap
ECU will also struggle to keep the turbo under control until remapped.
It will require a rescale for the injectors as at the moment it will be overfuelling.

Get it mapped and everything will be setup to suite the new mods.

Output depends how risky/aggresive you want the map.
320-330BHP will keep it safe @ approx 1.35bar.

yea that sounds good, still want it to be safe enough with out causing damage, the last remap it was runnin 1.2 bar, be happy with them power figures.

I honestly thought this was a wind up.

got the re map done today at power engineering, running at 324bhp, pleased with that, they said can probley get to 340bhp with a greddy profec b boost control, any ideas on whereto get one and how to fit?

Where did you take it? If its struggling to make/hold target boost then I would have thought fitting a 3 port solenoid would have been the ideal and cheaper option.
