Yea, and you can jam two fingers into an apple pie but that don't make it right!
I think you should flash back to stock and get a properly "balanced" tune.

Ok, so fixing your boost leak will magically make all your CEL's go away? A boost leak won't necessarily make your car die. You have more problems than that I suspect.

Can any one help ???
After a re-tune i have a torque imbalance problem and the computer will cut all power. I can re start but have to pull over and remove key. Computer will also cut PSM and ABS for no apparent reason
Car is mildly tuned standard turbos 5 bar fpr full gemballa exhaust evo intake plus a Y pipe GT2 Intercoolers and upgraded diverter valves, 920nm Clutch and wave trac limited slip diff.
Chassis dyno says 298kw and 852nm at the wheels. Approx 400hp and 628ft lbs.
Need help with the Torque Imbalance its not really a problem but would like it to stop as with the PSM ABS trouble.
I took it back to the tuner and he raised the torque limit 10% but with no sucess

sounds like you know very little about a 997, it has much more fuel then a 996 and much more. on the first page you said its boost is 1.4 now 1.2... you have K16's !!!! the max is 0.9-1.0, maybe 1.1 with a custom tune and race fuel... keep running your car with the set up it has , tune, OVER BOOST, and yeah it will run, for how long?? if you want more boost, change your turbos, tune, and proper upgrades to support them... there's not much you can do with a k16 car except add a few bolt ons to help you.. the biggest hit you'll get is the PROPER TUNE AND A GOOD EXHAUST!! .... WE HAVE ALL DONE THIS AND IF THERE WERE SOME MAGICI WAY TO GET THERE IT WOULD HAVE BEEN DONE!!!... save your $$$$, go with markski and its done... i'm sure if you blow your engine we will never hear about it on this post.... have your tuner put in writing that he will pay for your new engine and then do all the mistakes you want... doubt he will!!!! just so you know, i have a protomotive CUSTOM tune with K24 and wastegates... i run 1.2 bar on pump gas, and 1.4 on the race file with 60lb injectors....

I converted one of his dynos to SAE. It doesn't look bad to me especially if he says his car feels fine but you really need to see the datalogs to make an accurate evaluation, imho.

I wanted to do the same but don't have the right tool... great job! I tried reading tim's chart cross-eyed 
and didn't think the graph looked that bad. Like you said, the datalog will tell.
