"is tightly dependent" is correct and usable in written English.
You can use it when describing something that relies heavily on something else. For example, you could say "The success of this project is tightly dependent on the cooperation of all team members."
On the other hand, the FFT performance is tightly dependent to the processor's architecture and its memory and cache structure.
The answer is tightly dependent on the performance objective and on the network parameters, such as the transmission powers, channel conditions, etc.
We observe that the line defect induces the abundant Fano effects and BIC phenomenon in the electron transport process, which is tightly dependent on the width of the AGNR.
Env expression is tightly dependent on the host splicing machinery and is a limiting requirement for virus spreading and pathogenesis.
In addition, Akt downstream mTOR-p70S6K1 sisnaling is very important in CR because mTOR acts as a "metabolic checkpoint" in that its activation is tightly dependent on the presence of nutrition [40].
It is still unclear whether these differences were due to the use of a different array of SR proteins involved in RNA metabolism by gammaretroviruses, which rely mainly on single-splicing events, or lentiviruses whose replication and spreading is tightly dependent on multi-splicing events that govern the formation of key regulatory proteins [31].
It would probably come to an arrangement with the mighty oligarchs, but their crony-capitalism would be tightly dependent on the whims of the political powers that be.
Results suggested that pollutant removal (NH4 + and turbidity) was tightly dependent on the selection of environmental conditions.

The 'crystallizability', which is the ability of the polymer to crystallize, was tightly dependent on the exposure time and was used to follow the photo-ageing.
It is found that the line defect causes the abundant Fano effects and bound state in continuum (BIC) in the electron transport process, which are tightly dependent on the width of the nanoribbon.
