ive been considering moveing up to a stage 3 chip on my calibra turbo
im a bit stingey and was hopeing to use a vectra diesel intercooler which is sitting in my shed and cost me 10 quid
it does not look that much smaller than the one that comes with the kit but i am told that it is nowere near as good
so how much power will it lose me then and could i correct it by fitting 2 vectra intercoolers???
also how much boost does stage 3 use????
thanks in advance for your time on this matter
