Hi guys I'm very new to this I've only had this Scooby for 6 months I have put a lightened flywheel , stainless up pipe and decat road tested all fine no probs I have now put a polar performance chip ecu in it seems fine except when you really gun it she holds back a bit if I give it 3/4 throttle its perfect. I still have the original fuel pump but do have a 255 lph on order does anyone know if this will help or am I barking up the wrong tree thanks

 

Are you still running standard boost? could possibly be boost cut.

 

I dont think so I'm not sure how to alter that

 

Sounds like you need a proper remap mate, you've added some custom mods like the decat which needs mapping in and put an off the shelf chip on, get your fuel pump on and get a proper mapper to sort it for you
