Iv got a quite modded 2003 wrx, usual stuff, turbo, injectors, exhaust, fuel pump etc etc!

Anyway had my car mapped off duncan, and i love it!

only problem with my car is this wierd jerky splutter thing it some times does, only happens in 2nd gear when i plant the pedal! ie, out of a corner with an evo on my bumper!

Iv got a code reader which i will have a look at tomorro! But has any1 experienced this sort of thing before?

Thanks, michael

My 05 wrx had that exact issue and it was fixed when I got it remapped again, so I'd say it's something to do with the ECU/map.

MY99 had some emission thing and under certain conditions, think you had to be sat in 2nd gear a few seconds then plant it, and at WOT in 2nd gear cut boost to 50%.

Only happened in 2nd Gear. Not sure if this is same thing but sounds similar.

I reset my ECU and it stopped doing it but it was searchable on SN as an issue.

Yes this is exactly what my car is doin, its doin my head in, feels like some 1 stamps the brakes a few times then it goes!

Fuel surge IMO.

Low-ish fuel levels coming off a roundabout ?

How would this be fixed duncan?

More fuel in the tank - it is a common problem on subarus due to the tank design.

or fit a fuel surge tank and external pump

or fit a spec c baffled pump pick up.

or make sure that the fuel pick up in the tank is sitting on the bottom of the tank - it will still suffer from surge at low levels but it will make it better.

Al brim the tank and see if it still does it!

Im gonna book my car in for a tweak soon anyway mate. On vpower haha just gotta save the money now, as we have just bought a house, so pretty skint lol

Ive had the same issue with mine and ive got a 99uk 2000 awd turbo the issue was down to fuel pump as it dissappeared when I swapped the pump only happening again but I did use a used pump I have a new which will be fitted tomorrow will let you know how that goes
