Boost Problem

[arron2004]

Hi guys had a maf gon on my car couple months ago and it was not boosting correct as when i brough car it hit 15psi on a unkown map. Now i brought a new maf and it did not correct the problem so i unplugged it and used car with it unplugged for a while. In that time i fitted a pro alloy fmic. Now i have been payed i have brought a new maf and it hits 15psi and drops right down to 8-10 psi and does not feel no where near as quick as when maf was unplugged? i can see for boost leaks is it worth buying a new N75? no faults are coming up on vag com, or could it be due to the fmic ?

i don't know how much you make a month, but if your solution to all problems is buy something new and hope it works, then I hope a lot!

get the car on vagcom and start from there

he just said hes not getting any codes on vag-com..

 

[arron2004]

nice one cus! And reuvers i make enough to pass me buy plus the 1st maff came up as a fault on vag com and i did a little reading that this controlls your boost and can be a problem! I just went out in it now and it not even making 10 psi only 9 ish i gutted just really want to know how to sort this

When you fitted the Pro Alloy intercooler what map sensor did you use? Your original one or did you change it?

i used the original map sensor i think but there was one in the kit that i brought used off neils ibiza cupra but not 100 % on which one i used! Could my split-R need adjusting? as in its letting boost off to easy?

 

[arron2004]

i just fitted the other map and it has made no difference but that map sensor has spent a few nights out in the rain so is it worth investing in a new 1? I found out who the map/chip was done with chipped uk .com so i not got a clue! Could do with some one local to have alook for some beer tokens

 

[arron2004]

any 1 ?

Just checking. You need to keep the original Ibiza sensor and not use a 3bar one.

yeah i looked at the graphs looks well dodgy! i only have got the trial version of vag com, shall i invest in the full version to check the idle under boost?

so happy today car fixed.

as you may have read guy's i was having some problem's with my boost. It was going up to 12psi and dropping to 6 and not going any higher. So after a new maf and coil pack's and plug's which it needed it was still not boosting correct. So again i checked for boost leak's none found. Replaced map sensor. Still not boosting. But i unplugged maf and it boosted up to 14ish psi as befor. So i double checked maf no faults. Yesterday my new induction kit jetex come. And what a diffserence it's boosting to like 16psi pulling harder and better than ever befor. It feel's like a new car to drive.
