thanks for all your input guys.
car now has standard map back on and Forge spacer now off.
it's now as standard as t day it arrived. .
I'm taking it down MK to superchips head office next week and let then do t re map again and run it on there RR.
I did do t spacer up tight but I'm sure that where I was loosing t pressure.
Thank you all for your suggestions. If you still think it could be somethin else pop it on.
sounds a good plan mate but with the dyno lottery superchips rollers give massive power claims on cars iirc they had a rolloing road day and a stage 1
cupra made something like 360 bhp and a stage 2+ made nearly 400 lol
so you will come away thinking all is right and have a big smile on your face thinking you have good numbers but you are not comparing eggs with eggs.
And your
problem might still be there.
if i were you i would let seat look at your car with the fault stored on the ecu and go from there , have peace of mind knwing nothing is wrong before you map again and get it rolling roaded , also speak to forge about your spacer , you may have a dodgy 1 or the wrong one , eliminate 1 thing at a time , i know its frustrating but makes the best sense imho.
