How do I get 400whp reliably in 7AT 2011 370z

Jordo!

As one who has previously boosted a NA car and gone through all the experimentation, excitement, sucess, and failures, let me share with you one piece of advice:

Don't do anything to your car that could break something you can't afford to repair.

In other words, if you don't have the money to rebuild a blown engine/trans, why are you spending the cash to boost it?

It's less of a gamble boosting a factory FI motor/trans, as they are already built stout enough to handle the extra stress of FI, and simply retuning/increasing the boost a bit is less likely to cause a problem.

Anyway, maybe in reality it's only a 1% chance anything will fail -- but unless you have the cash to cover it, why take the chance?

After all, this is why we have warranties and insurance -- to protect against the slim chance something goes wrong during normal driving. Unfortunately, if something goes boom from an aftermarket FI set up, fixing it is your problem (Note: Possible exception: Stillen...)

Anyway, if you have the money to burn -- by all means, go for it. Worst case scenario, something breaks, you'll get it repaired.

First thing you have said I agree with. Bottom line is, if you boost, something will break. The new power will find a weak link and expose it. Not just on the 7AT but on any car. We are basically doubling the HP of the car and it wasnt designed to handle double.

This isnt unique to the 370 as my brother has the new camaro SS auto and is facing simlar iisues if he decides to boost.

Its always a risk to boost. Make your own decision.

+1. My general rule with FI is take whatever budget you think you are going to spend, and triple it. Stuff breaks and goes wrong all the time.
