help: threw a cel after apr stage 1 upgrade

[treemolecule]

i got my 04 1.8t chipped the other day, it runs fine for a whole day of daily driving, today i pushed it up to around 4500-5000 rpm on the freeway in 2-5 gears, some point in there i threw a cel, it runs fine, sounds good, i think maybe the throttle body needs to be aligned because its all or nothing on the boost. any help would make you a...kick a*s person and thanks in advance

Most likely a bad MAF. It might have been on it's way out and the chipping pushed it over the edge.

should i get an OE replacement or larger?

Um how about you get it vag commed before you start buying mafs.

Thats the best way of going about things

[Groove1797]

why are you running a MBC?

[treemolecule]

-well, it is kinda common sense to diagnose a problem before buying parts, especially when its only a CEL and not the MAF light.

-I ran MBC before I tuned to APR 1 so i coult get to 11 psi, should I still use my n75? if so is there a more stout n75 than stock?

[Groove1797]

APR is designed to run with a n75. There is no reason to run a different n75 except the stock one. Get the mbc out

hahahah

[treemolecule]

shut up. my audi loves me dangit. i'm going 1+ but i need tt225 inj. first, and i cant find any around town. anyways all of you seem to have provided nil information as to why this is happening, thanks for that, hahaha indeed, but if anyone could help me with this other than VAG com, thanks.

[audipotential]

The answer is to get it vag-commed.

That is all. Were not human diagnostic machines so go get it vagged and then post the results.

[treemolecule]

Yay, short concise answer with minimal to moderate sarcasm, thank you, now i know wtf to do. i'm not used to other people not being superhuman

[manguyen]

<<<<< for TT225 injectors.

[treemolecule]

im pretty sure i've got it taken care of, there was a tear im my DV hose so I taped it up and re-sealed everything from the TIP up, reset the CEL and it's not back since. hoo-freakin-ray.
