I have a 996tt in which there is supposedly a gemballa flash, together with gemballa exhaust, evoms v-flow and evoms dv's.

The question is - how can I tell if I have a remap?

Exhaust, V'flow and DVs I can see but how about remap. I keep reading these should show around 0.7 stock and 1.0 with a flash.

What if my car shows between 0.8-0.9?

Here is a short vid of a 3rd gear pull from today:

Is there a chance there is no flash and it is just thanks to the exhaust and intake that boost managed to get a bit higher than stock?

Or is it a very gentle flash?

What do you guys think?

 

It should be peaking at about 1.2 and level off around 1.0 with a flash. I have peaked at .9 on stock car with new DV's. It is possible you have a small leak in the system. That would prevent you from making full boost.

 

How do I look for boost leak in a 996tt?

 

You will need to take it to someone that can do a pressure boost test with an air compressor.

 

Mark where are you?

Pressure test it for sure!

 

I just fixed the same issue on my car. It was also supose to have a 1bar flash (i have a high flow exhast and EVO divertervalves as well) I would see 1 bar quick peak and then .8 bar. Installed GT2RS intercoolers and decided to pressure check the intake and make sure the wastgates were in sync while the bumper was off. I followed the directions from this post for the pressure test:

Good thing I did the pressure test as I had not got the intercooler hoses all the way on and they popped off. Found two pretty good leaks. One was at the F-hose and the the other was a small line. The wastegates had been tightened more than they should (Backed them off from 33MM to 31mm).

When I test drove the car I was getting 1.4bar spike with a constant 1.2bar. Ended up backing them off to 28mm. now I get a quick 1.2 spike with a constant 1.0 in higher gears.
