I have a 3 port solenoid and a nice boost from 27psi up to 25psi at 7000rpm on stock turbo, RC 750cc, Injen CAI, 3" Perrin downpipe with catback and HKS muffler, Carbonetics twin disc clutch, AMS engine mounts and Torque rear diff mounts, AFR is 10.8-11 and tuned timing.

The problem is that the car does not pull as it should, is it possible that the Air Flow Check and Torque Limiter tables to cut down the power ? like gradually closing the throttle ? The best quarter mile time I got was only 13,1s with a good launch.

Why I am suspecting the torque limiter and air flow check tables is because it builds up boost very fast and it holds the boost very easy up to 7000rpm, it's like the throttle is not fully open.

 

You should be able to tell if the throttle plate is closing by logging the TPS.

 

That is what I want to try tomorrow.
The car was faster with lower boost and now after I have installed the 3port with much higher boost in at high rpm is slower, also no knocks, just 2 sums at 5000rpm and 1 after 6500rpm

I could not find any good info on Torque Limiter tables.

 

With higher boost, you are hitting different load cells compared to before. So you might want to fine tune your Ignition Timing and fueling map to maximize the performance.

Also did you disable the various DTC 1233-1241 tables?

 

I have not disabled any tables, how to disable them and why? because I don't get any CEL
The timing and fuel map are set for that load (at about 230 load), I set the timing until I got knock then backed up until no knock.

 

The torque limiter kills the car completely. You would know. Car goes into limp mode and won't rev past 3k rpm.

 

Perhaps a boost leak at the higher boost?

Low boost doesn't leak thus feels faster, higher boost leaks plus the air gets rather hot as the turbo is essentially over-working.....

Just a thought. My IX was like that when I had a leak. 18psi tune ran circles around the 23psi tune. Noticed the car pulled a bit harder as I let off the gas. Eventually figured it out. Check your IATS to see if it's too hot as well.
