GR Yaris Mods And Dyno

We have this lovely GR Yaris in the Whifbitz workshop last week for a couple of mods, we fitted an Airtec catch tank kit and an Airtec header tank.

Whilst it was here the customer wanted a power check to see what its making with the mods fitted and remap he had done elsewhere, its got an Eventuri intake kit, intercooler, gpf delete, exhaust, decat pipe and remap done somewhere else, we would normally see around 330bhp with these mods but this was only making 309bhp with it also missing a massive amount of low down torque and power, he will be back soon for one of our custom Ecutek tunes no doubt!
