Whats wrong with my scoob??
I fitted a Scott Tayor chip to my 93 wrx ra at the weekend. Car started fine with no warning lights coming on.
I cannot really tell if it feels any quicker but it now hesitates at around 4500 rpm, it was fine before with very smooth power delivery. I changed the pump for a walbro 255 but that made no difference(i thought it was leaning out at high revs)
Any idea's i know there is not much to go on.

The increase in boost pressure (chip associated) may have highlighted a problem with your coil-packs - meaning they could be 'breaking down'
Remove the coilpacks and check under the rubber shroud which goes over the plug - if there are any cracks in the ceramic then they are likely to be the problem
