Hi can anyone help please i've got a 03 wrx with remap 255 fuel pump panel filter and back box i decided it would be good to have my first go on a quater mile at shakespeare county raceway i had 3 runs the problem was everytime it was great of the line 2nd &3rd gear but when i got in 4th it seemed to loose its power i looked at the boost gauge and did not appear to drop boost but was lacking and wouldn't pull like the rest of the gears my first thought was maybe plugs there 3month old 6's or could it be something else thanks in advance: )

 

Does it run fine?
It may just be the gearing and the TD04 running out of puff by the time you get to 4th. Alternatively heat soak

 

Hi yeah the car runs fine it was fine driving home. Probably a daft question when you say heat soak what would be getting too hot anything particular?
It was a hot day so could it be just one of them things ?
Thanks again

 

Little quick update I've just gave my car a test as its a cool night tonight compered to Sunday and it ran fine in all gears could this mean the intercooler was too hot on Sunday?
