I'm just wonder if all the tunners play with the same boost levels. What boost are you seeing with your modified ecu's (please, mention all the other performance mods)?

Alex (UK)

1.0 bar normal mode, 1.2 bar sport mode. I didn't see these before the powerkit went on.

TT Surgeon

1.0/1.2

I run 1.4-1.5 bar on race gas depending on weather. Iam running EVOMS GT660 with EVOMS ICs. 996TT

TT Gasman

1.0 Bar/1.2 Bar sport, sustained, Ruf ECU.

It is important to know that the dash gauge does not read higher than 1.0 in standard mode and 1.2 in sport mode. You could be boosting 1.4 and the gauge will show only 1.2 in sport and 1.0 in standard.
This applies only to the 997TT not the 996TT.

With stock ECU is use to see only 0.9/1.1 bar (normal/sport modes) and only for 1 sec or so.

With my CG ECU I now see 1.0/1.2 bar and it stays there whilst my gas pedal is fully down.

The CG remap is meant to add 0.15 bar more than stock so you are certainly right on my 1.2 figure actually being 1.25 or even higher but the display only showing 1.2 still.

AAHTT is right,
997 TTs only go up to 1,2 bar

My car goes to 1,65 on overboost, and 1,55 constant

I use a Blitz electronic boost gauge. It spikes occassionally to higher levels, (1,8 to 2.0 bar !!!) but these values are not real and are not taken into consideration
