1.6 bar stage 1 WTF!!!!

[R4cup]

My car has been suffering with over boosting issues for the past few months so i decided to turn the little screw on the N75 to see if that would cure it which actually made it worse as the car will not boost over 0.5bar.

Now that i have replace N75 my car is peaking at 1.6
Since ive noticed this i have been taking it easy as i dont want the litle ko3 to go pop.

Why is this? anyone........

for stage 1 it seems higher than I would normally see.

 

[daves ibiza]

thats what i thought as my las map was aggresive and only made a bar

 

[R4cup]

anyone heard much about zender clamping the Map sensor?

as EZ Tutty(user on here) has solved his overboosting via this........

 

[daves ibiza]

what you mean mate

 

[R4cup]

my stage 1 runs 25psi (26psi on odd occassion) or at least it did run that until my boost problem appeared over last few months.

 

[black magic 20v]

when i first put my boost gauge on it was peeking at 25 psi but it only peeks at 22to20psi! and thats only a stage 1 custom code map!

1.6bar taken from boost gauge?

i dont trust boost gauges at all.

Yeh but its been reading just over 1.3bar before i changed the N75.

Im going to swap it the weekend so i will take it from there.

it didn't fix my overboosting, it stopped the ECU seing the extra overboost from running an N75J valve. mine peaks about 1.5-1.6bar depending on gear...
