Hi,

Does anyone know what sort of boost pressure the stock ecu is mapped to cope with..is a chip essential if i wanted to run about 11 psi..

:nono: get a chip before turning boost up talk to john dixon he will sort u out with one :D 1 bar max on standard tubs :cool:

Your likely to be safe up to about 12psi, although if its an Import then your risking detonation without getting it proplerly mapped for Uk fuels, plus you wont see the true potential without a decent remap.

 

for the sake of £75 I would get an uprated chip fitted.

you wont be able to turn boost up with the stock chip, stock chip programed to about 9psi so thats all you will get, even with bigger tubs.

 

stock tubs ok up to 1bar of boost pressure, to get this you have to re chip the ecu and engine re mapping + you will ned an electronic boost controller so you can adjust the amount of boost you want up to what the chip is made for

I ran approx 12psi for a year on a Jap ECU and it was absolutely fine. A uprated chip will give you better performance and safer running conditions though.

like he said boost controler not mig tip mod spend abit its safer cos cuting corners will cost u big time
