afew Qs
 

iv just bought a japspeed down pipe this will complete my full decat system..(turns out it already had a uppipe)

now as the car is it pulls quite nice off bottom but i feel the power tail off up top...is this the cat strangleing the car??

as a rule what sort of gain has been seen from decat..

will i get boost spike?? im chipped at 1.1bar at the mo..

ok Q2...acuator (i cant spell) iv read that there should be no slack???
so am i understanding that if i un clip the arm..there should be no free movement??..

What chip do you run currently? And what mods are you supposed to be running with that chip?

If I were running a chipped ecu I would try to ensure and run a parts setup that is precisely what that tune is supposed to be as a first step.

i have 1 of silversurfers polar performance chips... was set up to run full system decat i believe....

by monday my spec will be

full 3inch exhaust decat and up pipe
walbro fuel pump
syntec fpr set at 3bar
polar performance chiped ecu set at 1.1bar
