I have a 1999 a4 1.8t quattro.

im not sure what the stock psi is but i do want to raise it without a chip and with out putting a FMIC on it. I am told i can get a manual boost controller to crank up the boost. If i did this what woul be the most psi you would push on stock everything.(i also have a drop in K&N, if that makes a difference)

i will have my boost gauge soon and a controller soon after.

What should the stock psi be? and with just a boost controller whats the most psi SAFELY??

thank you and im sorry for the noob question , i just got the cat last week.

 

Ask cincytt i think thats his name on here, but other then that, id say searh, then NO, then your a noob, then get a chip and stop trying to do things the hard way!

 

Unfortunately, 97-99.5 1.8T's don't have a MAP sensor. This means that the engine won't adjust for the added boost very well and you will run lean. Instead, you need a chip to remap the fuel and timing as well as boost. I also run an MBC with my chip just to get a little extra boost. The MAF and o2 sensor seem to be able to compensate for slight increases in boost, just not large increases.

 

You need a chip. Its much cheaper than a blown engine.
Giac is pretty popular for your year.

 

go for the chip, and supporting mods you wont be dissapointed

 

No map means you need a chip. you can get neuspeed or someone less if you dont feel like spending $500+ on a chip. I think their's is like $300. Its made to pass Cali emissions so its not as (i hate saying this) agressive as the others, but you can fix that by just matching the psiwith more boost with a mbc.

 

Ok thanks guys.

But are you saying if i put a MBC on i could turn the boost up a couple psi without a chip?. Just not any crazy psi?. IF i put a MBC on would i be able to turn up the boost at ALL?. If so, how much?. Thank you.

and what are some cheap chips to get, im on a budget(since im 17yrs old)

 

get a boost gauge first thing and then save up and get a good set of wheels and drop best first mod ever

 

how do u recomend dropping it? with what brand b/c i am wanting a smooth ride stil

cost?
