Need help after new mods

I I've had a heap of new parts installed. 1000cc Injectors, new 68mm VTG's, headers, exhaust, Y Pipe, plenum, 82mm throttle body and clutch.

Car pulls really well in 1st and then in 2nd it feels really flat and as if it's not boosting 100%. I've had Dzenno complete several maps and he can't see anything wrong.

Does anyone have any suggestions as to what may be the problem? I've done a boost pressure test and all seems well!

Thanks for any help in advance.

I am waiting on PTF to come back to work from holidays Monday as well to try E85. They have done an amazing job so far on the tuning with 98 RON octane for my setup. Did you send them any logs of what you mean?

That was my first thought. Makes a bunch of power,.. heat-soaks the IC's after just a ouple of gears,.. then the ECU pulls a wad of timing.
.
But his tuner would see that immediately in the logs of the IAT's I would think.

Thanks for the replies!

Car has Champion Intercoolers at the moment.

Is there a way to test the BRV's?

Check your FPR as well - sometimes it may come disconnected and this could be one of the symptoms.
