I don't recall your model/year...
But in the first two gears, I think that you have lots of low end torque. But in hot weather, it is probably not so impressive.
I would be concerned with any amount of hot air induction with your filter setup in warm weather. I have insulated my intake plumbing, air box, pipe from the IC and the throttle body to a practcal extent. This does help a lot in hot waether, but nothing replaces winter torque.
If you have an older model, the Viggen IC might provide a significant improvement. Certainly if you ever did upgrade the turbo, you would need that in place.
I do share the concern with the autobox. I guess that they are shy about the turbo upgrade and any news of trany problems. But with an Abbott ECU you still have some low gear torque limiting.
I suspect that what you are after is more torque at higher RPM's. The stock turbo probaby cannot deliver the CFM's to maintain torque at the high end.
I also suspect that Abbott might be limiting boost to some extent for a autobox ECU.
So if your boost pressure drops with high RPM's, I would suggest the Viggen (or Abbott) IC to keep the temperatures down and density up.
If the boost pressures are not dropping, then at the high end I would also be concerned with temperature and air charge density. The new Turbo is a big step, and the IC should be done as a final solution or as a prerequisite to a larger turbo.
If your needs are in the lower end, not WOT high RPM's, then you need higher pressures, and a MBC on the Abbott ECU would be worth trying, but the autobox would see the max torque in the low gear and probably would be as risk.
So I guess the upgraded IC is where I would see myself going from either direction. With that, yo might try a MBC with sane boost levels and that might fill in the bottom torque and throttle response needs. An MBC will transform the response characteristic quite a bit.
If you are into street racing and quarter mile advantages, you need CFM's and more charge air cooling. Try an upgraded IC first, then an MBC, then a turbo if you need to have agressive torque at 90 or 100 mph.
With your apparent budget, the IC makes sense. My budget is more humble ;)
