First thank you to all that have responded to my posts.

STill no stinkin boost

installed the apr a box ecu ..Tested on a friends s4 worked great!

Pressure tested .. would hold about 10 psi and slowly bleed off
2 new 710n's

I swapped out a working n75

also swapped the n249 with a working unit

installed a vent boost gauge it has been reading 20 inches of vac when I hit the go pedal it moves to 10 inches of VAC. NOT UNDER A LOAD.

I guess I will have to try it under a load to really check.

total vag com newbie please give a step by step on what I should look for next

Take it for a drive - without killing yourself do the following: Pull at WOT: watch the boost gauge for the maximum psi it attains, then watch and see where it levels off. Try this on a clear straight part of road with little traffic. Report back with the results.

WOW ugly ...no boost what so ever lots of vac 20 inches and then just gets to zero yes zero boost and goes away!

donromani

Do you have any indicator lights? Can you pull codes?

rktskicar

codes would be good. Need logs as well (block 115 VAG).

deeprecon1

Ok I will get on pulling the info.

I got no codes at this time. I have not had a code since doing the cats.

I will use the vag com to log block 115.

Thanks guys ...

Just to clarify, you are not getting any boost at all under load, even at WOT? Is your car performing accordingly, that is, as if it had no turbochargers?

deeprecon1

There is NO boost underload! Runs like it has NO turbos.

donromani

And when did this start? Did you have this problem before you swapped out the ECU box?

Have you ever replaced your MAF?

deeprecon1

No on the MAF.

Yes it was running the same with the first a box.

I got the car it was running like crap... very little power.

Felt like it was plugged up .. that's when the cat delete was done.

CATS gutted muffler on I could now hear the turbos at rev and at wot. I only ran the car hard once after they were gutted.The turbos worked just fine. I then drove it gingerly back to the house, I then got my first codes .... the start of the issues.

Put in the spark plug no-foulers and no more codes.

Got a P0300 MULTI MISFIRE code replaced bad plugs wrong ones were in the vehicle. No more codes to this date.

Cleaned My MAF with autozone MAF spray.

Have not had a code since .. like a week.

I also do not have the muffler installed right now. No oil in exhaust.
