AEM gauges (Digital):

Hey guys, i got some gauges recently placed into my car and i am currently UNTUNED and have a appointment scheduled for next week for the tune. What are the proper readings for the boost, air/fuel, oil pressure gauges after i get the tune?

Currently i am reading around 80PSI on my oil pressure gauge when im on the highway and around 40PSI on side streets.

My boost though is different.. At idle or side street driving the boost is negative 16.9 to -22PSI. I recently got into boost shortly and got up to +16PSI. I am thinking it is because of the untuned situation i am not in the 20's?

Currently my Air/Fuel gauge reads 14.59. What should this reading be with a proper tune?

What should all the gauges read with a proper tune? I will be installing the Grimspeed Boost as well at the shop.

Thanks!

 

Anyone?

 

Your looking for trouble going into boost untuned.

I have 3 cars. This one will sit until it is tuned. My tuner is about 40min away i will drive it there safely and slowly.

I was just curious on what the gauges are supposed to read after the tune. But googling answered my question.

 

Are you getting tunes for pump or E85?

 

Pump. 93 oct.

 

Looks like you've been here a while. A quick search will tell you everything you need to know.

 

Don't know about oil pressure but AFR should be reading around 14.6-15 at idle and around 11 under WOT. Boost reads in inHg when in vacuum (idle) which varies depending on your intake. If you're using a Cobb OTS map you shouldn't be hitting more than 24 psi

 

Oil pressure: warm idle at 20psi, cold start 60psi, cruising 80psi
AFR: cruising 14.5, WOT I can hit 11.5 as my tuner (Cobb) was very conservative and I am on 93 for now.
Boost: Idle -20psi, boost...that's up to your tuner. I hit 28 and taper to 19psi at redline. Stock turbo but full bolt ons.
