I wouldn't be giving it any till I got it on a dyno and looked at.. Esp when it isn't happening with the std tune is flashed in, means the 11psi tune isn't right.. Are your spark plugs gapped to .8mm?Generic tunees aren't any good as all cars are different and react different to the same mods done... basically your mods on my car would require a different tune to run right..Xcal 1's as the others have said are worthless now, you could buy a xcal 3 for around $700 and get your ecu tuned, or VCM or Sniper to get the ecu tuned, not sure how much that costs though..

(check all are fine)- blocked cat? ( there is some heat discolouration and some people think it sounds blockd but others dont?)- fuel injectors ( not coping with 11psi? or just old or blocked? (full tank of bp 100 octane and injector cleaner)- spark plugs and gapping (done)and ive heard rubish about disconect ecu battery etc etc and over boost, factory ecu cut out, traction controll...and now valve spring issues..mind you my car now has 150,000kms could any of these things mensiond just be old and this happens?

My walbro when near 1/2 a tank would surge, drop power as if traction control kicked it, ran rough for a while too.. Who fitted it? some places don't know how to fit these properly and with the right hoses too.. Edited 29/01/12 06:50 AM by MiKa Link to comment Share on other sites More sharing options...
