Boost Spikes - Should I be worried?
Advice would be very much appreciated.
Live in albany, and as many would know it can get pretty cold and wet compared to perth. Just tonight I was coming home and on full boost I spiked to 1.2bar for half a second. It has done it before during similar conditions but only to 1.1bar and only on a cold night or in the wet. Is this a problem? Why at roughly 17.4psi would I not hit boost cut? (If the gauge is acurate) There are no boost controllers fitted to my car that i am aware of, car is pretty stock apart from 3" tbe, SSQV and Apexi Pod. Normal boost is around .9 bar. I wasn't really worrying before at 1.1 bar cause thats close to boost cut, but now it's gone to 1.2 bar which is past boost cut. Cheers in advance |

Not sure why it is spiking??? But as for the fuel cut, it doesn't come in straight away. When I first put my manual boost controller on it was running about 17.5 psi. The car ran fine, but tended to fuel cut under hard accelleration in 3rd gear, but only after about a second and then it would come back on boost again. If it is only spiking on the odd occasion you prob wont get fuel cut.....

It only does it when the air outside is cold.
On a normal day it will be fine, but once the air outside drops below aprox. 20 degrees i start to get spikes, which i herd were normal, but all they way to 17.5 psi? |

yer thats very tru, on colder nights u will run more boost due to the colder air being more dense and making the turbo boost harder and u will hit cut very often had the same prob wid me car get a aftermarket ECU man and a EBC thats the only way to solve it.....
took me for ever to realise but i have made the change and should work a treat |
