[Zas)-(]

HELP PPL

i have a turbo smart dual stage boost controller in my engine bay....

i've slowly just got how to actually read the guages of.. 0.5 bar etc

..now...

i recently got defected so i had to plug up where the blow off was and now i have a stock airbox with knn filter material...

i recently was toggling with lower n higher boost up n down..... and found out da car went up to 18 psi. remember i have 4 inch all da way thru so no probz dere n it was all good when the previous ownder had da car

my prob came when i increased the boost to max and then gave it to it...

now my car wont go past 4 thousand revs it just diees .. like keeps rolling but at lower revs.....

WATS HAPPENING???

any ideas???

do you have a stock turbo?

perhaps you raped and pillaged the ceramic exhaust wheel?

Ive heard that you cant safely put stock turbos past the 14psi mark (absolute maximum). so that would be my geuss.

Ummm is that a stock everything? if so well for starters it will kill the turbo doing that kind of psi and your motor wont be too happy as well. The standard ECU will fuel cut as well.

Please give us some more details, and learn to type properly.
