so i'm chipped with giac, and i notice that in the lower gears (mostly second while im at about 3-5krpm and not flooring it) ill get some surges every now and then from the turbo. i dont have a boost gauge in yet [:@] , but i think its the boost spiking irregularly. would a n75 help? and if so, is there a way i can make sure my car doesnt go into limp mode?

 

ha. haha. haha. oh. im sorry. i had that exact problem. get a boost guage. your boost shouldnt be jumping, but that dont matter

YOU PROBLY HAVE A BOOST LEAK!!

open your windows and get there in the boost, and see if you hear a wshhhhhhhhhhh noise when you are in the boost. u ahve a leak

or ur turbo is going. i had a leak. fixxed it surging went away. my turbo is taking a sh*t now and it surges again. i hate life lol

 

hmm nope, no boost leak, and i doubt my turbo is going at 46k

i think imma either gonna try a mbc or a n75j

 

before you get a new N75 or MBC get a boost guage...it should be the first thing you buy with a turbo car, next should be a turbo timer

 

ehh id do a turbo timer if i had a bt or something of the like... i think its a waste of money. all you gotta do is not drive like an @$$ for the first and last few minutes of your ride

 

hmm not drive like an ***...ill take that into consideration haha. but yeah definetly get a boost guage it will be so much easier to diagnose future problems

 

on a side note check out www.boostvalve.com for an MBC its what I have and I get no surging at all and its very easy to install and use

 

thanks tooxtreme

 

what turbo do you have what giac file, and is the N75 valve stock?

 

giac flash upgrade, stock n75
